Isaiah 65:24 (NKJV), "It shall come to pass That before they call, I will answer; And while they are still speaking, I will hear."
I sponsor an underprivileged child in another country. She sometimes sends me a letter with a prayer request. One prayer request in particular had to do with their rainy season. By the time I received the letter, the season had come and gone. At first I felt it was too late to pray, then the above passage came to mind. I realized God had already answered my prayer because He knew I would be calling on behalf of my special little friend.
You may be asking why I would even bother praying if God already answered my prayer. The Bible says in James 4:2, "... you do not have because you do not ask." God is outside of Time, He can answer our prayers even before we ask, but we still have to ask. God knows all things. He knows our needs and has given us access to everything we could ever need through prayer
Jesus said in Matthew 16:19, "I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven." We carry the keys. We have been given the authority to release heaven on earth. If we do not release it---heaven is bound. The power of God is not released.
God has restricted Himself by giving us dominion on this earth. Just as we have to choose His free gift of salvation, we have to choose to release Him into our affairs. He has given us the avenue of prayer to release heaven on earth.
Pray. You are an avenue for the full power of God to be released to a world that truly needs it. You have your own set of keys to access it.
