Of course we can't be "LIKE" God ....as in sharing the same status, glory and power ,...neither should feel a need or WANT to be like Him (a better word is that we should be "AS' Him,...LIKE-minded).....that is what OUR spirit should be.
We should be ABLE to IDENTIFY with Him as a SPIRIT living INSIDE OF HIM (Him in us and us in Him...His spirit in the inner man.
