All in Mysteries of God

How is our faith constructed? Who are we without Jesus Christ, and the Holy Spirit? Wasn’t it God’s plan from our inception that one would come to us then the other? That we are saved, and redeemed by Christ, and led by the Holy Spirit, so that in this way we can once again walk with God, as Adam walked? Isaiah prophesied regarding the coming of Jesus, and it has come to be. He also told us that God’s Spirit would come to us, and that too is now true, but is there more than this? Is there a mystery to solve?
