To Whom Is He Revealed?

Let us muse today from John 17:6 and the High Priestly Prayer. I want us to ponder today the subject of to whom is the Lord revealed. We saw yesterday salvation comes through a manifested revelation. We are told by our Lord that He does not reveal Himself to all but unto those which thou gave  me out of the world. Our Lord said they were Yours and You gave them to Me as a gift. The question arises when did this transaction take place? When comparing Scripture with Scripture, Paul tells us in Ephesians 1:4, and the Father chose a people before the foundation of the world and place them in His Son.
