Jesus uses an interesting phrase here. In fact, it is the only time he uses this phrase in the Gospels. And it is used 3 times within these 4 verses. He says, “you will die in your sin.” This is a phrase the means that IF there is sin on your life and you physically die, that sin on your life condemns you to hell. The Bible tells us that the consequences of sin in our life is eternal separation from God. If you die with sin on your life you are going to hell. That is the great despair that we live in as humanity. Now I said, “IF” there is sin but here is what we need to understand, “every single one of us are sinners. We were born sinners.” The moment that you were conceived, you were conceived into sin. The moment you were conceived, sin condemned you to hell. But just because we were born condemned, doesn’t mean were have to die condemned. Romans 6:23 says, “For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.” Jesus came to this earth to pay the penalty for our sins. Through his death on the cross, He took the penalty for our sins. He died in our place. And in His resurrection, He defeated death. And we can have the condemnation of sin removed from our lives when we repent of our sins and place our faith in Jesus as the only one who can forgive our sins and give us salvation. And so even though we still have a sin nature and we will die with those sin natures, when our lives are in Christ our sins have been paid for and we have been given the righteousness of God. At our physical death, we stand right before God. But if we choose not to repent of our sins and place our faith in Jesus Christ we will die in our sins. Our sins will condemn us to hell. This is the position that the Pharisees were in. They were rejecting Jesus as the Messiah, as the son of God, as the one who could save them. This is why Jesus said, “I am going to leave and you are going to keep looking for me.” Since they were rejecting Him, Jesus told them very directly “you will die in your sin.” It is interested that he said “sin”–singular. He is referring to a specific sin and that specific sin is the rejection of Jesus as Messiah. It is the sin of unbelief. It is the sin of God revealing himself to them through His Son and them rejecting this revelation of God.
