What is the difference between believing God can do something for us and believing that he wants to do something for us? Would you call the difference faith? or knowledge? or both?
I believe it is both. Faith, I believe is number one with knowledge coming in at second.
I accepted Jesus into my heart when I was a child, I lived on a farm and saw Jesus' work through the birth of new baby animals and every year the crops growing out of the plain black dirt. I knew that only One person can do such things. God! I would see my Grandparents pray for a good crop and at most times all worked out for good. I believed and had faith in God that He wanted to do things for us. I had faith that anything is possible when you ask God.
But then, as I got older and the reality of adulthood set in, I lost the faith that a child has. But around 10 years ago I started going to small group Bible Studies and began to learn more about God. Reading His stories such as this story about the leper, shows that when we have faith, God will provide if it is in His will. I also learned that God wants us to ask Him for things, He wants to bless us and show us His love and power. But I also need to remember that some of the things I ask for might not be in His will, because He knows what is good and best for me. I have faith that God will always do what is best for me! He knows me more than I know myself. I need to stay in prayer and in His word on a daily basis. He has so much to tell and reveal to me each day.
