What the Bible says about All Sin Is Committed Against God
(From Forerunner Commentary)
We recognize the true seriousness of sin when we realize that all sin is committed against God. But another serious effect is that it is committed against oneself (Habakkuk 2:9-10; I Corinthians 6:18). Our bodies are not our own; Jesus bought us with His own blood. So we must glorify God in our body and in our spirit, which are His (I Corinthians 6:19-20).
