Have you ever told a 'white' lie? Even the nicest person has told lies. The Bible (Revelation 21:8) says that lying is as bad as robbery and murder and that the same penalty applies to each. You may not be a bad person in human terms, but do you judge other people by their actions? If so, why then should God not judge you for your actions? (Matthew 7:1-5; Romans 2:1-3).

Sin is not represented in the Bible as the absence of good. Sin is more than unwise, disastrous behaviour that produces sorrow and distress. It is rebellion against God's standard of righteousness (Ps. 119:160). Since God demands righteousness, sin must be defined in terms of mankind's relation to God.
God has put laws in place to protect His creation. These laws are the Ten Commandments (Exodus 20:3-17). By breaking just one of these commandments we are disobeying God and bringing God's judgment upon ourselves. (James 2:10)

Violation of the law of God in thought, word, and deed shows the sinfulness of the human heart. Sin is actually a contradiction to the holiness of God, whose image mankind bears. (Acts 17:28; Galatians 5:19) The moral character of a man's actions is determined by the moral state of his heart. The consequence of this rebellion is death and the torment of hell. Death is the ultimate penalty imposed by God for sin (Rom. 6:23).

Hell was intended as punishment for Satan and his angels not for humans. (2 Peter 2:4). However people with unconfessed sins will go to hell as they are unfit to enter heaven. (John 3:3; 1 Corinthians 15:50). Our corrupt mortal bodies cannot dwell in heaven without contaminating it for heaven is a perfect place.

It is imperative that every unbeliever recognise the truth that the Lord Jesus Christ will hold him accountable in proportion to the degree of opportunity that he has had to turn from sin to God. We are all going to be judged for our actions by God (1 Corinthians 4:4). As our creator, any crime against a human being or their property is a crime against God - no matter how small or insignificant that crime may seem. Written in every mans heart is the knowledge that one day he will be ushered into God's presence in order to give an account of himself. The Bible tells us that God will punish all crimes on the day of judgement (Revelation 20:11-15, Hebrews 9:27)

Maybe you think that because God is "good" He will overlook your sins.
For example:

A man says to a judge:
"because you are a good man will you overlook my crimes even though I am guilty?"
The judge responds by saying:
"because I am a good man, I cannot overlook your sins, therefore you will be punished."

This shows us that it is God's goodness that will be the very thing that condemns us on judgement day. Because God is good, He will punish murderer's liar's thieves etc. and they will go to hell.

As God is our ultimate judge, He is also the only one who can completely forgive all our sins (Mark 2:7). The gospel comes as the good news of the deliverance that God has provided through His Son. Jesus bears the penalty of sin in place of His people (Mark 10:45). He also redeems us from lawlessness and makes us long for good works in service to God and others (Titus 2:14).

However there is a catch - we must ask God to forgive our sins, which means we must first acknowledge that we have sinned and fallen short of God's glory (Romans 3:23). It is absolutely important to everyone's eternal destiny that his or her name is written in the lamb's book of life - the book which lists the names of those who have repented and been forgiven by God and thus have a ticket to heaven. It is not that our sins are somehow minimised or overlooked, they are simply forgiven and forgotten by God. Those who are foolish enough to pass up this free ticket to heaven are reserving for themselves a spot in hell.
