“But you, keep yourselves from the things devoted to destruction” (v18). Just as Rahab (the foreign prostitute) and her people made the choice, by faith, to join the Israelites and escape the destruction of Jericho, the Israelites themselves faced the reverse choice: they could disobey God and embrace the poisoned objects of Jericho, forfeiting their share of God’s blessing. By His own power, God caused Jericho’s walls to fall, yet the Israelites had to desire to be part of His victory.
“See, I have given Jericho into your hand” (v2). Our most difficult “Jericho” might not be external, but rather an internal struggle against sin; God wants to give us the victory.
