If not, then please explain what Paul mean when He said,
Php 2:5 Let this mind be in you, which was also in Christ Jesus:
Php 2:6 Who, being in the form of God, thought it not robbery to be equal with God:
From what I see above, it is not a sin or a bad thing to think that we are equal to God, but are commended to have the same mind or thoughts that Jesus had, and in so doing we are NOT taking anything away from or robbing God of any glory or credit for the works done. We too are made in the form of God, for Paul said we are, and as sons and daughters, who being in the form of the most High God, are made partakers of His divine nature through the knowledge of the promises of His word. In that respect, we are equal to God. No, we are not God, but we are little gods of THE GOD, for Jesus said we are.
If I design and oversee the construction of a building when I hired contractors to do the specialized work of erecting it, can't I say that I built it? Of course I can and do.
If one country goes to war with another, who takes the credit for winning it? The head, leader, strategist, or general. Did they do the actual fighting. No, but they take the credit for winning the war, don't they?
Did Jesus Himself do the actual healing of the people, still the storms, or create all things in existence? No, but because He is over the one who did the actual healing, stilling, and creating, He can and does take credit for all that was and is done, because not only is He the head, but the initiator of the work as well. If Jesus didn't command the storm to be still, it would have raged on. The same goes for them who walk by faith with corresponding works. They initiate the work by, at the very least, speaking to the storm or thanking God that it is done.
It is written that the forces or issues of life flow from or come out of the heart. It was the same with Jesus. The woman with the issue of blood initiate the work for her healing, but it was the Spirit or virtue that proceeded out of Jesus that did the actual healing. We have this same Spirit that Jesus had, only our is not without measure like He had.
So yes, God does the actual work of stilling the storms, but we must first command it to be done in the name of Jesus, as He told His disciples to do. Why do you think He got mad at them for being fearful, or why He told them to feed everyone, when they had very little food? We need to stop thinking of ourselves as sinner slaves and serfs saved by grace, as though we have absolutely no power or authority through the name of Jesus and the promises of God's word, and start seeing ourselves as sons and daughters of the Most High God.
