Peter was overwhelmed when he saw Jesus walking on the water, and he wanted to do it too.  While there is really nothing wrong with his desire, what he asked Jesus was totally wrong.  He didn't ask Jesus if He wanted him to walk on the water, or if his faith was strong enough.  Instead he said, "If it be thou, bid me come unto thee on the water."  What was Jesus going to say, "It isn't me. Don't come."?

There are no other examples of someone walking on water in the Word of God.  Jesus had a definite reason for walking on the water; but, Peter just wanted to see if he could do it.  God will permit us to do things that are not His perfect will for us.

Many times we hinder our own prayers by the way we ask things of God.  We say, "Do you want me to do (a) or (b)?"  The Lord may not want us to do either one. 

We should offer Him a third choice (c) His will for us.  We should trust God's wisdom and even allow Him to select the options.
