Was the sending of the twelve spies into Canaan part of God's plan?
No. That reconnaissance mission was not part of God's plan at all. God intended Israel to trust Him explicitly after He miraculously brought them out of Egypt and through the Red Sea, and He planned to lead them straight into the Promised Land without delay.
Les teaches that the sending of the twelve spies into Canaan was not part of God's plan at all, even though most casual Bible students do not understand this. God intended Israel to trust Him explicitly. He had already brought them out of Egypt miraculously and through the Red Sea, so the Canaanites, even if seven or eight feet tall, were no problem for such a God. As soon as the tabernacle was completed, which would be in a year, God wanted them to raise it up and take them right straight north into the Promised Land. There was to be no delay with twelve spies or any such thing.
