Achan answered Joshua and said, “Truly, I have sinned against the LORD, the God of Israel.” –Joshua 7:20
The Israelites experienced a resounding victory at Jericho. So when they were crushed at Ai, Joshua couldn’t believe it. He cried out to the Lord, and God explained: “Israel has sinned, and they have also transgressed My covenant which I commanded them. . . . Therefore the sons of Israel cannot stand before their enemies” (Joshua 7:11–12). Remember, a man named Achan had disobeyed God by taking some of the plunder from Jericho for himself. Achan’s sin brought defeat to the entire nation. When his sin was found out, he said, “Truly, I have sinned against the Lord, the God of Israel, and this is what I did: when I saw among the spoil a beautiful mantle from Shinar and two hundred shekels of silver and a bar of gold fifty shekels in weight, then I coveted them and took them; and behold, they are concealed in the earth inside my tent with the silver underneath it” (vv. 20–21). Notice how Achan described the progression of his sin: “I saw.” Sin always begins with the eyes. Now, seeing and admiring something of beauty is not in and of itself a sin. But we get into trouble when we fixate on what we see. “I coveted them.” To covet means to desire something that is outside of God’s will for you, whether it is wrong under any circumstances or simply wrong for you right now. “And took them.” If you meditate on something that is outside of God’s will for you, eventually you’re going to act on that desire. Wrong thinking leads to wrong action. “They are concealed.” We all inherited from Adam and Eve the urge to try to hide our sin from God. But as long as we conceal our sin, we can’t heal from our sin by receiving His forgiveness. To Achan’s credit, he eventually named and claimed his sin. You cannot truly repent until you see your sin the way God sees it and call it what God calls it. Adultery is not merely “a lapse in judgment.” Addiction is not “overdependence.” Lying is not “stretching the truth.” To receive God’s forgiveness, you must agree with Him about your sin, just as Achan did.
