Achan’s sin affected the whole people of Israel: ‘the anger of the Lord burned against the people of Israel’ (Joshua 7:1). Sin is like infection – it spreads! What kind of effect do your actions have on other people? Cain asked, ‘Am I my brother’s keeper (Genesis 4:9). His question was an expression of callous indifference. There is no place for this attitude among God’s people: ‘Decide never to put a stumbling block or hindrance in the way of a brother’ (Romans 14:13). Read the story of Achan, and remember this: ‘Be sure your sin will find you out’ (Numbers 32:23). Let no one have good cause to ask, ‘Why did you bring trouble on us’ (Joshua 7:25).
