Let him deny himself

source

Went looking for the source of a story that Robert E. Lee, asked by a mom for advice on raising her boy, said “teach him to deny himself.”

From Douglas Southall Freeman’s four volume 1934 R. E. Lee: A Biography.  The source cited is one Joseph Packard’s Recollections of a Long Life.

Original source probably one JC:

And he said to them all, If any man will come after me, let him deny himself, and take up his cross daily, and follow me.

Luke 9:23, KJV.
