Joshua 7

So Joshua rose early in the morning and brought Israel by their tribes, and the tribe of Judah was taken.  He brought the clan of Judah, and he took the family of the Zarhites; and he brought the family of the Zarhites man by man, and Zabdi was taken.  Then he brought his household man by man, and Achan the son of Carmi, the son of Zabdi, the son of Zerah, of the tribe of Judah, was taken. vv.16-18

Read chapter 7
Achan's sin.  Just after the Jordan River waters were split for Israel to cross and then the fall of Jericho, no sooner did the Lord's anger burn against Israel; and no one knew or understood why.  Joshua seems so confused seeing they lost in battle against Ai when he knew the Lord's promise and deliverance.  Thankfully God tells Joshua why  and it's because of someone's sin.  Notice it's not like a court system today of trying to prove who committed the sin, but God boils it down right before their eyes to the one single man: Achan.  He knew he wasn't suppose to take the plunder of Jericho and covet, yet he did anyway probably justifying himself it was okay for we see his repentance of knowing what he did.  What may be hidden to man is not in the slightest hidden to God.  I wonder if Achan was in any agony before he was convicted by God?  When have you tried to hide a sin from not only people but from God?  What was the outcome?  Even though Achan admitted his wrong he still had to face the punishment: stoning.  We don't read that his admitting was a repentance, yet either way we thank Jesus for taking our due of sin.
