But if you do not do so, then take note, you have sinned against the Lord; and be sure your sin will find you out. (Numbers 32:23, NKJV)
The tribes of Israel, which on the east side of the Jordan River, were commanded by God to help their brethren subdue the land of the Canaanites before settling their own territory (Num. 32:20-22). Failure to obey the Lord’s will would mean they had “sinned against the Lord.” Omitting God’s will from our lives is sin against God (James 4:17). Furthermore, we cannot hide our sins from God. We are accountable to Him for every one of our sins. We may hide our sins from others, but we will answer for every one of them to Almighty God. Everything is open to His eyes (Hebrews 4:13). This becomes an incentive for us to “lay aside every weight, and the sin which so easily ensnares us” so that we may “run with endurance the race that is set before us” (Hebrews 12:1).
