Many people don't realize that Genesis 1 is many things. One of the things it is, is an allegory describing what we all should be - (children of) God who create things. Genesis 1 also indicates how we should go about creating things: we should call them into being. The above is consistent with Christ’s instructions on how we should have faith:

Mark 11

22 Have faith in God," Jesus answered.
23 "I tell you the truth, if anyone says to this mountain, 'Go, throw yourself into the sea,' and does not doubt in his heart but believes that what he says will happen, it will be done for him.
24 Therefore I tell you, whatever you ask for in prayer, believe that you have received it, and it will be yours.

So we can create things by calling them into being (while believing what we command will come to pass), or we can ask God for things (while also believing what we ask for will come into being).

The above singular act (having faith in God), is what transforms a man/woman into (a child of) God. It is what: saves him; gives him righteousness and makes him righteous; subjects him to trials and sacrifice; empowers him; makes him wise; etc. The life of a child of God, is all about practicing having faith, and accomplishing greater and greater things with it. All the transformations, sacrifices, etc. that happen to a  child of God, unfold naturally, as a result of his pursuit of faith – as Christ instructed how it should be done, above.
