Did God Lose The Plot ?

Did God take leave of his senses? 

If God is the almighty creator of the universe, what would possess Him to to be born as a helpless baby, to put himself in a position of complete dependence on human parents, to make himself vulnerable to all the pain and suffering of life on earth?

What on earth would be the point of it?

What sort of God decides to do something like that?

It's noting more than the power of love !!
