The heart is dynamic, not static. It is always moving in one direction; toward either sensitivity or callousness. In Mark 3 we read the account of a Sabbath showdown between the Pharisees and Jesus.
“Then Jesus asked them, “Which is lawful on the Sabbath: to do good or to do evil, to save life or to kill?” But they remained silent.” Mark 3:4
The confrontation is over the healing of a man with a withered hand. The text says he was angry at the hardness of their hearts and after the healing of this man they allowed their hearts to harden further. The condition of our hearts is fundamental in loving God and man. So I ask, what is the condition of your heart today and where is it headed?
