Get up, sanctify the people, and say, “Sanctify yourselves for tomorrow, because thus says the LORD God of Israel: ‘There is an accursed thing in your midst, O Israel; you cannot stand before your enemies until you take away the accursed thing from among you.'” Joshua 7:13
Just as the obedience of one Christian can bring blessing to others, the sin of one Christian can bring harm to many others. The children of Israel were rapidly advancing into the Promised Land. They had experienced a miraculous victory over the city of Jericho, and they were continuing toward their next conquest. To their surprise they met decisive defeat as they attempted to capture the small town of Ai. They sought God’s explanation for their failure, and He provided it. He revealed that someone among them had disobeyed His clear command not to keep any possession from Jericho. The disobedience of one man and his family had paralyzed an entire nation! Achan thought he could conceal his sin and it would not affect anyone else. God chose to demonstrate the destructive power of one sin to His people. One act of disobedience cost Achan and his family their lives. It caused his countrymen to lose the battle; innocent soldiers were killed. His sin had serious repercussions for others, denying them the blessing, power, and victory of God.
Your sin will have an impact on others. Choosing to disobey God may cost your family God’s blessing. The power of God may be absent from your church because you are living in disobedience. Your friends may suffer because you are not living righteously. Diligently seek to obey every word from God, for you do not know how your disobedience could affect those around you. Scripture promises that if you will obey the Lord, your life will be a channel of blessing to others (Ps. 37:25-26).
