Willing was willing, but not able. And Able was able, but not willing. The farmer never got any work done because he needed mules that were both willing and able.
For us to get our prayers answered we must believe two things. We must believe that He is able to answer our prayers, and we must also believe that He is willing to do it. We just can't believe one or the other. We must believe both.
King Nebuchadnezzar threatened to throw Shadrach, Meshach, and Abednego into the fiery furnace unless they bowed down to the golden image he had made. In Dan. 3:17 they responded, "Our God who we serve is able to deliver us from the furnace of blazing fire; and He will deliver us out of your hand, O king." They believed He was both willing and able.
In Matthew 9:27-28 a couple of blind men asked Jesus to heal them. Jesus asked them, "Do you believe that I am able to do this?" Why did He ask that? Because whatever we are asking for, we must believe that God is able to do it. In Matthew 8:2-3 a leper said to Jesus, "Lord, if You are willing you can make me clean." He believed He was able to do it, but wasn't sure if He was willing. Jesus said He was willing, so the leper was healed.
What are you praying for? Do you believe He is able to do it? Do you believe that He is willing?
