All things are possible if you believe
Jesus said "All things are possible to those who believe". Because Jesus is God and God can't lie then it means the inverse "nothing is possible if you don't believe" must also be true. Put simply if you don't believe God can do it then He can't and won't do it. The problem is not God because He can do anything and specialises in the impossible - the problem so often is our unbelief. It says in Matthew 13:58 that Jesus could do no miracles there because of their unbelief. Think about that for a second... The supreme creator of the entire universe who is limitless in power couldn't help those people for one simple reason... Unbelief. So the key to seeing God do that impossible thing in your life is seeking Him and believing He can do it. So can God do the impossible? Absolutely. Does God always perform the impossible at our request? No. Sometimes He has a greater plan for us and asks us to trust in Him. He doesn't leave us hanging and will always give us an answer either yes or no to those who seek Him. It comes down to relationship. He wants us to ask and believe. So... Ask and Believe God for the impossible. He can do it. God loves you.
