God is an unchanging being in the sense that he will never "change his mind" or modify His word. He preaches the same gospel with the same ordinances & laws to every dispensation. The amount of how much of the gospel we are taught depends on the people and how much they are ready to obey. But both Heavenly Father & His Son do still continue to progress & increase in glory. And no matter what anyone may say today, Joseph Smith very plainly taught that God was once a man like ourselves!

Looks like no one has brought this up yet, so here's a source from General Conference back in 1885 when they talked about this very thing. Hope this helps shed some more light on this.
