Question:
Is there a verse in the Bible that says that all sin is equal?

Answer:
Romans 6:23 says that sin brings death, even if we only commit one sin: “For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.

James 2:10 says that if we break one of God’s laws we are guilty of breaking all of God’s commandments: “For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.”
