Mat 16:17 Blessed art thou, Simon Barjona: for flesh and blood hath not revealed [it] to you, but my Father which is in heaven.
This is one of the few verses that Christ addresses to a specific person but, as always, the lesson is for all of us. In the previous verse, Christ makes the distinction between public views and private views, infering that the public is wrong. Here Christ tells why. We don't get the truth from our relationships with other people. The truth comes only from our relationship with God, the spiritual source. Our relationships, especially our public ones, somehow conflict with the truth.
Alternative version: Good for you, Simon Barjona, for your relationships with people have not uncovered this for you but my Father who is in heaven.
