We are summoned to follow him. At the same time we are summonsed to follow him. So far from the mindlessness of sheep-like conformity, Jesus insists that we think . Ponder for a minute the place scripture gives to thinking. Think about the place scripture gives to the mind.
Discipleship never means sheep-like stupidity, unthinking conformity.
Discipleship always includes the most rigorous thinking, thinking infused by the truth of God and oriented to the kingdom of God. Over and over in the written gospels we come upon our Lord summoning people, inviting people, to follow him. Matthew stood up, left behind whatever it was that was preoccupying him, and followed. So did James and John, Peter and Andrew. If you and I are resolute in our following then we can only keep looking at Jesus.
