Joshua 1:9 AMPC
[9] Have not I commanded you? Be strong, vigorous, and very courageous. Be not afraid, neither be dismayed, for the Lord your God is with you wherever you go.
Just picture the man Moses, and how Israel must have viewed him as he led them from Egypt to the land of promise. The people of Israel had seen how God used him in parting the Red Sea for them to walk over on dry ground, while the army of Pharaoh all perished in the sea. They had seen Moses do mighty works in the wilderness, from amazing supply of manna and water for the whole of their sojourn in the desert, to the glory of God being made manifest at different times. There was this incident on Mount Sinai where the glory of God was so obvious that the people of Israel were trembling with fear. In all of these encounters, we read, like a footnote, of the man called Joshua. First time this young man was mentioned was when Israel had to fight Amalek, and Joshua had to choose men to fight. Joshua did as commanded, and God gave victory. Do not despise the days of small beginnings.
A few years later, the same Joshua was at the foot of Mount Sinai, at the tent of meeting, and as one of the emissaries sent to spy out the land of Canaan. In all of these encounters, we see the young man being trusted to represent Moses well. I am not sure this man was in any way interested in replacing Moses, and I can imagine how he felt when the mantle of leadership was being placed on him. He had seen Israel rebel, and even though he had not joined in the rebellion, he had also wandered with the whole of Israel for 40 years. He had seen what disobedience did to Aaron and his sons, as well as to Miriam the sister of Moses. He had witnessed the punishment of Korah, Dathan and Abiram. How could anyone lead such a stubborn and rebellious people like these? This is where God always steps in. The One who commissions always knows what is ahead, and He is the One who supplies what is quite appropriate for the vision that He has birthed.
This is what the verse above is all about. God knew that the shoes that Moses was about to take off was big, but then, it is not about the capacity or ability of the one who would fill the shoes, but the capacity and ability of the One who gave the shoes in the first place. God knew what was ahead, and before the pressure would build, and discouragement would come, He came to reassure Joshua. No man can do God's work without the help of the One who commissions the work. No man can survive on His own. I need the presence and power of God to achieve whatever is His will. He knows the scope of the assignment, and He knows the lives that need that which He has given me. When God commands, all that I need for life is supplied. His name is at stake, and be sure that God can back up His name. He will not leave me alone to fend for myself, whilst I am at work for Him. I must not let the world dictate relevance. With God on my side, and as I obey His leading, I am where He wants me to be. That is impact. Am I where He wants me to be? Are you? God's time of favour is here.
