It is not so much faith that is important but the One in Whom you place your trust. What is important is trusting Jehovah-Nissi, (the Lord our banner) for He has promised to fight for us, when our enemies come in like a flood.
As Israel's armies fought Amalek, their fierce enemy, on the field of conflict in the physical realm - in the same way Moses battled the adversary in a parallel sphere, through spiritual warfare. As the Israelites fought their physical enemy with sword and spear, so Moses battled a spiritual enemy in the heavenly realm - through prayer and intercession.
As Israel raised weapons of war against their bitter foe, so Moses lifted high the Rod of the LORD against the principalities and powers in heavenly places. The earthly foe would be overcome in the spiritual realm. Victory or defeat would be determined by the effective prayer of Israel's faithful watchman.
Just as soldiers raise their battle standards high, proclaiming allegiance to king and country, so Moses lifted up His Banner to the Lord. Moses raised up the Rod of God to proclaim Whose they were and Who was their true Champion. The Lord God was their Defence and Defender, and so they fought under the authority, direction and power of God, Who from that day on, became to Israel, Jehovah-Nissi :The Lord Is My Banner.
The arms of Moses grew weary and the legs of this prayer-warrior weakened as he travailed in intercession for those in his care. Spiritual warfare is intense, and the arm of flesh fails when we face the enemy's onslaught in our own strength. But as Joshua and the armies of Israel continued to battle the Amalekites with swords and spears - so the weary arms of Moses were held aloft until sunset by Aaron and Hur, to enable Moses to keep the rod of the Lord raised up against spiritual wickedness in high places, for only as he interceded for Israel was their victory secure.
It was as Moses prayed for the people of Israel that the enemy was overcome. Although he grew weary and rested his exhausted body on a Stone, Moses kept the rod of the Lord lifted up in prayer, so that we finally read: Joshua overcame the Amalekite army with the sword.
We too fight under the same standard, for Christ is our Banner. We too lift high the name of Jesus, for He is our Rod and our Staff. We too rest our weary soul in Him for His is the Rock of our salvation -and He is our strong Tower, to Whom we flee for safety.
Like the armies of Israel under the leadership of Joshua, we are not to rely on our own strength, for Christ's strength is sufficient for all the difficulties and dangers that we may face. He is the One upon Whom we are to cast our heavy burdens and rest our weary souls for Jesus won every spiritual battle we will ever face, when He proclaimed from the cross - It is finished.
Thank You Father for the spiritual lessons I can learn from the faithful saints like Moses and Joshua, Aaron and Hur. May I recognise that in everything Jesus is all I need and that under Your banner I can face the future in full assurance and peace. I pray that my prayers and intercessions will be underpinned by Jesus my Rock and upheld in truth by Jesus my Saviour, in Whose name I pray, AMEN.
