Able is the Greek word dunatos, related to dunamis, meaning ability,
abundance, capability, mighty works, miraculous power, prevailing strength. "God is able" means God has the mighty power to do a miraculous work out of His abundance and strength. Romans 16:25 says God is able to establish you. Listen to the richness of the verse when read with its full definition "God has mighty power to do a miraculous work out of His abundance and strength to establish you."
Bring your inability to the ability of God. As you read these verses drink in the bigness of God as you replace "able" with "has the mighty power to do a miraculous work out of His abundance and strength."
