(2Co 3:2) “Ye are our epistle written in our hearts, known and read of all men:” Notice closely: He didn’t say, “written on your hearts”, but “my heart”. The Holy Spirit enabled him to love them in such a way as to make them very much a part of himself. What does that mean? He would then give of himself for himself (them) in a way above what one can normally do. That….is seen in his entire ministry.
