Matthew 9:29 Then touched he their eyes, saying, According to your faith be it unto you.
This is a strong statement. He healed them because they believed. He rewarded their faith. They came to Him believing. He responded to their faith. So the measure of their faith had much to do with what Jesus did in their lives.
Do you believe Him? Will you believe what He says in the Bible? Just believe and trust Him. Watch Him answer your prayers and do great things in your life.
