Jesus says, recorded in John 14, "if you have seen me you have seen the Father also." In Matthew's Gospel it is declared that Peter says, "thou art the Christ the Son of the living God." This declaration comes from a Revelation of the Spirit of God and not of Peter's own ability. In Galatians 1, The Apostle Paul declares that God revealed His Son IN him. And finally in II Corinthians Chapter III and IV, the Apostle Paul declares we are changed (transformed) by beholding the glory of the Lord.
Seeing Him is everything to our walk. We can only see Him by the Spirit. Seeing Him is the way unto transformation. To have a changed (transformed) mind and heart it takes the Lord. When our heart turns to Him, we will see. John turned and saw according to Revelation 1. Sometimes what we turn from is our own religious beliefs to see Him. He is the light to our souls. We are to come and walk in the Light that He is. Glory to God!
