Mark 9:23 (KJV) 23 Jesus said unto him, If thou canst believe, all things are possible to him that believeth.

All things that are authorized by God for mankind. We have limited possibilities, God has unlimited possibilities.

What is impossible for mankind is possible for God. What we can't do, God can do. We are limited, God is unlimited. Man can do some things

Angels can do some things, God can do all things.
