Christians who believe in God have assurance in victory.
Rahab the prostitute (Joshua 2:1) believed
that Jericho would be conquered by the Israelites (v. 12).
The reason was that she believed that the God of the Israelites,
Jehovah, was the greatest God in the world (v. 11).
Christians who believe in the greatest God in the world
have the assurance of victory.
