Without controversy, the mystery of godliness is great: God was revealed in the flesh, Justified in the spirit, Seen by angels, Preached among the nations, Believed on in the world, And received up in glory.
So now as He returns to the Father, He is promising that He is going to send to them the Holy Spirit. One who would come alongside of them to help them. "I will leave you without help," He said, "But I will pray to the Father, and he will give to you another Helper, even the Spirit of truth; whom the world cannot receive" ( John 14:16 , John 14:17 ). And He tells us that when the Spirit comes, we will receive power. What kind of power? Power to be like God. Great is the mystery of being like God. You cannot be like God with your best effort no matter how hard you try. It isn't within our nature or our power to change our nature to be like God. The only way I can be like God is through the power of the Holy Spirit working in me and changing that nature.
