There is a very big difference between someone who is a father and someone who fathers. Rather than simply adopting us into His family and letting us be, God desires a continued growing father/child relationship with you. Jesus talks about how children ask their earthly fathers who are inherently evil for things and their fathers give them those things because they love them. How much more our Heavenly Father longs to give us things, but we must first ask. And when God gives us things we must not take it for granted, but rather always give Him thanks, because the gratitude of a child to a father makes the father delight all the more in blessing his child. Lastly, our bodies are temples of the Holy Spirit, of who is equal with the Father, and therefore we should not grieve Him by taking part in actions that He would want nothing to do with.
