Q: Suppose a Christian did something really sinful, but died in a car accident the same day before they had a chance to repent and ask God for forgiveness. Will this person still be saved?

...And if the answer is yes, then won't haven be a non-perfect place because that person still hasn't been forgiven of their sins, but still entered the Kingdom of God?

A: This is quite an interesting question!  Let's tackle it one step at a time.

Yes, a Christian who did something very sinful and died in a car accident before repenting will be saved.  You have to remember that salvation does not rest upon a constant confessing of every sin a person has ever committed.  When we place our faith in Jesus Christ, the Scriptures tell us that we are granted salvation.  We do not have to keep on asking for forgiveness in order to maintain our status of being saved.  Look at this passage from Colossians 1:13-14

¹³For he has rescued us from the dominion of darkness and brought us into the kingdom of the Son he loves, ¹⁴in whom we have redemption, the forgiveness of sins.

This passage clearly outlines the fact that Christ has brought us out of darkness and into the light and we have been redeemed by His sacrifice.  This sacrifice results in the forgiveness of sins.

So having established the fact that we are forgiven of our sins once and for all through the sacrifice of Jesus Christ, a Christian who has full knowledge and acceptance of this is redemption will enter heaven "clean".  The need to literally and legalistically ask for forgiveness and seek repentance after each and every time we sin is unnecessary since we have been given grace already.  However, a mature Christian should possess an attitude of repentance in which he/she recognizes that they are sinners and accept the need for a Saviour.
