Sin is described in the Bible as transgression of the law of God and it is of the devil and rebellion against God.
Sin is the nature of a wicked and a characteristic of a Devil and who has gone spiritually away from God . We should continuously pray to God at all times to deliver us from all evil And guarding our self not to have fellowship with the unfruitful works of darkness. The sins are always to be confessed, repented, mourned truly in order to be a righteous before God. The Bible lists many things that are sinful in God's eyes.

The Bible commands men to depart from all sin, to keep God's commandments, to be holy because God is holy, and to be perfect as our Father in heaven is perfect. The Bible teaches that all men ought to live without sin and that they can live without sin by God's grace and the power of his indwelling Holy Spirit. The Bible also teaches that Christians do live without sin and overcome the world, the flesh, and the devil.One can live without sin. Here are some scriptures ref.Awake to righteousness, and sin not 1 Cor. 15:34

Little children, sin not * 1 John 2:1

Shall we continue in sin? Romans 6:1, 2

Go, sin no more * John 5:14; 1 John 8:11

Stand in awe, sin not * Ps. 4:4

He that committeth sin is of the Devil 1 John 3:8

Whosoever is born of God doth not sin 1 John 5:18; 3:9

Jesus hated sin and he hated worldliness. He put up with the sinfulness of men in order to call sinners to repentance.We can even cultivate relationships with the godless for the purpose of calling sinners to repentance and evangelizing them, but never to enjoy their sin or sinful life style. Paul said this to the Ephesians in Eph. 5:3-8, II Cor. 6:14-17

We are not to socialize at all with people who, having become part of God's Church, are practicing sin. Jesus was compassionate for sinners because Christ came into the world to save sinners. He didn't come to make sinners feel good about themselves.

Some people attempt to justify their wrongdoing by saying, for example, that Jesus refused to condemn the woman caught in adultery and that He spent much of His time eating and drinking with sinners.

Jesus' words to the adulterous woman, "Neither do I condemn you" (Jn. 8:11), are filled with forgiveness, not tolerance. She knew her own sin, and He knew that she did, whereas the would-be stone-throwers weren't reflecting upon theirs. So Jesus had to deal with them first. But after He forgave the woman, notice that Jesus did not say, "Go, follow your feelings, celebrate diversity, and try not to hurt anyone." He said, "Go, and sin no more." To the paralytic, He added a further warning: "Sin no more, lest something worse befall you" (Jn. 5:14). That God was reconciling the world to himself in Christ, not counting men's sins against them. And he has committed to us the message of reconciliation.2 Corinthians 5:19

Do not be a lukewarm Christian rebuke the sin, judge righteously. One does not need to have lived all his life without sin in order to rebuke others. Jesus knew His disciples had committed sins, yet he still ordered them to rebuke sin (Matthew 18:15, Ephesians 5:11, John 7:24, James 5:19,20,).If we fail to rebuke others when they sin, then we ourselves have committed the sin of disobeying the above verses. We learn that the Bible forbids certain kinds of judgment, but it also requires us to rebuke sin in order to help people please God and be saved.

Whosoever is born of God will not commit sin. And saints are made free from sin to become the servants of righteousness. The word of God, prayers keeps away from sins and also we need to keep as far away as possible from sinful places and sinful people who corrupt good morals.

1 John 3:9 whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.

1 John 5:18 We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.

When God says he hate sinners it does not mean that he will tolerate the sinners or the sinners go unpunished. Love for sinners is not reason to keep quiet about sin. The Bible says that Sin should always be confessed ,mourned over,hated,departed from, Avoided even in appearance from all forms,shoulded be guarded, to be prayed to keep away and delivered from sins, to ask God to cleanse our sins with the Precious Blood of Jesus Christ. Christ not only pardons repentant sinners, but He restores in them the image of God.

God loves the sinner when the sinner is purged from his sinful nature. God will receive any repent sinner that comes through Jesus Christ. A true love for sinner is by speaking the truth in love, correcting him, rebuking his sin and not allowing a person to live in sin or continuing his sinful lifestyle. The godly sorrow we feel should cause us to change our minds about the way we have acted and lived in the past. Our sorrow should make us decide to quit doing what is wrong and start doing what is right. This is repentance.

John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.

Romans 5:6-8 for when we were still without strength, in due time Christ died for the ungodly. For scarcely for a righteous man will one die; yet perhaps for a good man someone would even dare to die. But God demonstrates His own love toward us, in that while we were still sinners, Christ died for us.

Jeremiah 23:22 But if they had stood in my counsel, and had caused my people to hear my words, then they should have turned them from their evil way, and from the evil of their doings.

The wicked people encourage themselves in sin and also Delight in those who commit sins. They also have numerous unbiblical excuses to commit sin and to defend their sinful ways. When you question them they mock and boast about their sins also they try to tempt others and they either blame God others for their sinful natures. They have become spiritual Blinded which is caused due to the effect of sin, a work of the devil and Leads to all evil. When God's people do not obey Him, He allows a spirit of blindness to come over them.

Psalms 64:5 they encourage themselves in an evil matter: they commune of laying snares privily; they say, Who shall see them?

Isaiah 3:9 The shew of their countenance doth witness against them; and they declare their sin as Sodom, they hide it not. Woe unto their soul! for they have rewarded evil unto themselves.

There are six things the Lord hates, seven that are detestable to him: haughty eyes, a lying tongue, hands that shed innocent blood, a heart that devises wicked schemes, feet that are quick to rush into evil, a false witness who pours out lies and a man who stirs up dissension among brothers" (Proverbs 6:16-19).

Pride, envy, gluttony, lust, anger, greed, and sloth are considered as The Seven Deadly Sins because it is believed they can do terrible damage to the soul.

True Christians should honestly grieve over personal sin and repent of it and try to take measures to avoid it. We are told that we are forgiven of past sins, but it is not ever stated that we are automatically covered for future sins. (Rom. 3:25, 2 Peter 1:9).

The Lord Jesus did not teach that all of our sins past, present, and future are automatically forgiven.

If one does forgive that person without his repentance, he is adding to his wickedness that is being committed by him and this will not produce love or any good. It must be understood that repentance must always be first to God and then to the offended member. Repentance means Recognition, Remorse, Rejection and willing to change as a new person. If there is remorse and rejection of a sin, but you don't recognize the hurt or damage you have caused other person who is a victim, it becomes sin. The root of it that is, it will come back cloaked as something else and cause you to commit the same hurt or sin. No one can force another to forgive. People have their own timing in forgiving.

Produce fruit in keeping with repentance. And do not begin to say to yourselves, 'We have Abraham as our father.' Luke 3:8

Every Sin Has Its Own Consequences: we see that Ham & Noah (Genesis 9:20-27) involved in looking at naked body Hence Ham's son Canaan and his descendants are cursed (future Canaanites).

Angels taking human wives (Genesis 6:1-12, Jude 6-7, 2 Peter 2:4) which was Indulged in gross sexual immorality with "strange flesh" and as as result Earth was corrupt and full of violence God determined to destroy humanity by a flood .

Once saved is always saved states that once a person is truly saved through repentance and faith in Jesus (Romans 10:9), his or her salvation can never be lost no matter how badly or how often that person sins after salvation. Many times in Scripture we are told to continue, or to persevere in our faith. Sin separates us from God:Isaiah 59:2 But your sinful acts have alienated you from your God; your sins have caused him to reject you and not listen to your prayers.

Galatians 5:19-21 :The acts of the sinful nature are obvious: sexual immorality, impurity and debauchery; 20idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions 21and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.

Sin provokes God's judgement, Genesis 19:12-13.The two angels had left Abraham talking with the Lord about the possibility of sparing the cities of Sodom and Gomorrah from judgment (Gen. 18:16-33). Upon entering the city of Sodom, the angels saw firsthand how degraded the inhabitants of the city had become (Gen. 19:1-11).

The men of Sodom thought the angels were men and demanded to have sexual relations with them. Lot offered to give his two unmarried daughters to be abused by the men of Sodom if they would not molest these angels. This is a disgusting and vivid illustration of how deeply sin can take people into degradation. A good man can do terrible things if he turns away from the Lord.

The angels had a solemn warning for Lot. They had been sent by God to destroy the city. Lot must take his family and leave immediately. The angels made it very clear that the destruction of Sodom was an act of judgment from God because of the greatness of its sin. God's judgment on sin is a neglected theme in today's culture. However, God still judges sin. God is love (1 John 4:8), but God also punishes the sinner and hates all who do iniquity.
