Moses called on Joshua to choose out some men for battle and go fight the Amalekites at Rephidim, and Moses would go to the hilltop and stand with the staff of God in his hand. As the battle rages, as long as Moses holds his hands in the air, the Israelites have the upper hand. But when his arms get tired and his hands are lower, the Amalekites have the advantage. Moses is joined by his brother Aaron and another man, Hur. When they realized what was happening, Aaron and Hur brought a stone for Moses to sit on and they stood one on each side and helped him keep his hands in the air. As a result, Joshua defeated the Amalekites at Rephidim.
As I was reading the story again, it hit me that raised hands are often a sign of praying, worshiping, and praising God (see Nehemiah 8:6, Psalm 134:2, 1 Timothy 2:8, and others...) As long as Moses' hands were raised, God's people were winning the battle, but when the hands dropped, the enemy gained control of the conflict. As long as God's people are praying and praising God we are winning the battles, but when we stop praying and praising we begin to be defeated by the enemy.
In this world, we will have trouble. We have been set free from the Egypt of our sin and we are journeying to a Promised Land of eternal salvation, but for now we live in a world infected by sin and infested by an enemy who seeks to kill, steal and destroy (John 10:10). There will be battles, and they will come when we are weary, tired and worn out from the journey. The key to victory in the battles is to pray, worship and praise the Lord until the victory comes.
Sometimes we will grow tired in the battle, and we will need some "Aarons" and "Hurs" to help us. We were never meant to fight alone, so don't resist help from God's people. And sometimes it will you who need to be an Aaron of Hur for someone else; don't let those opportunities pass you up - others need you too.
By the way, though the Amalekites were defeated that day, that wasn't the last time the Israelites had to fight them. But God made a promise that one day He would "completely blot out the name of Amalek from under heaven.” (Ex. 17:14) The battle you are going through now won't be the last one you will fight; the enemy will continue to harrass and attack as long as he can; but we have a promise from God that one day the enemy will be removed and will never disturb the people of God again (Revelation 20:10). Until that day, fight the good fight of faith, and use the weapons pf prayer, worship and praise to experience the victory God has promised you!
