“Ye are our epistle written in our hearts, known and read of all men:”
King James Version (KJV)
3:2 Ye are our recommendatory letter - More convincing than bare words could be. Written on our hearts - Deeply engraven there, and plainly legible to all around us.
2Co 3:2 Ye are our epistle. The church itself owed its existence to him. He could point to his work, to the disciples, as his letter of commendation. He was known by his fruits. Written in our hearts. When he looked into his heart, he saw them enshrined there, and felt that he needed no commendation to them.
