Clear away the rubbish, strip out the dead wood, straighten the twisted, distorted pathways of your heart,
That's a word heavy with negative connotations...regret, sorrow, penitence, penance.
But, the Greek word that Matthew uses is so much richer.
This word carries the sense of a whole change of mind, a change of heart. Something about a before.... and an after ….A happening, a reflection, and a decision.
