That's the thing, it's always about the easiet ones to keep. Why is that? For me, personally, keeping God's Ten Commandments makes me happy. And God does not change. Jesus is God in human form. Jesus showed us the loving side of God, whereas people think for the most part He's just jealous and angry.
"God has neither evolved, grown, nor improved. All that He is today, He has ever been, and ever will be. "I am the Lord, I change not" (Mal. 3:6) is His own unqualified affirmation. He cannot change for the better, for He is already perfect; and being perfect, He cannot change for the worse. Altogether unaffected by anything outside Himself, improvement or deterioration is impossible. He is perpetually the same. He only can say, "I am that I am" (Ex. 3:14). He is altogether uninfluenced by the flight of time. There is no wrinkle upon the brow of eternity. Therefore His power can never diminish nor His glory ever fade."

7. The Immutability of God
I don't know where you guys get the idea that God changes. The only reason why Christianity would "die" is because the people on earth find it too difficult to follow, and they want to find the easiet way.
The future of religion involves the Sunday Law having to be observed by everyone. It's either the Sunday way, or no way at all. Mind you, it's not like that as of current, but eventually it'll become a problem, especially for those who don't observe the Sabbath on Sunday.
Look in the past: The Crusades, Hitler attempting geneocide on Jews and Jehovah's Witnesses, and Monk's in Tibet being slaughtered because they stand up for what they believe in. It's already happened so far, and who is to say it won't happen again?
People will be persecuted for their beliefs, and that is what I believe the future of religion will bring. Whether or not a person conforms to the changes made so they're not persecuted is soley up to them. As for me, I'd much rather stand up for what I believe in, instead of changing because it makes life easier.
