“And he said unto them, Go ye into all the world, and preach the gospel to every creature.”
Imagine the mess and disgrace Moses would have had if he did not listen to the last command “GO” meaning; you are done and fully trained to go and face the enemy and set the children of Israel free.
During training, you might sustain some injuries, experience severe pain, make painful sacrifices but if you can endure, you will reign permanently over your enemies and subdue them.
Do you know how it cost Moses before God made him god over pharaoh? Obedience, he was always with God fasting and praying on the mountain, other examples; Joshua, David, the Apostles e.t.c.
NO TRAINING NO REIGNING!
