Jesus knows it is all about the heart. Jesus challenges us to get right with the core of who we are, out heart, as children of God.
Once we have our heart right, what we think and what we say can follow. That level of alignment is what we know of as integrity. As mature children, it is essential.
“A good head and good heart are always a formidable combination. But when you add to that a literate tongue or pen, then you have something very special.” ~~Nelson Mandela
