Being a Christian, a disciple, is simply following Christ.
If you have ever taken a road trip involving multiple vehicles, you know what it means to follow. On the long straight-aways of open highway, in broad daylight, you can feel a little freer to slow down, to go at your own pace. But, it only takes a few curves, the setting of the sun, or hitting rush hour traffic for everybody to quickly close the gap on the leader. There is typically panic in the car until we are once again riding the bumper of the lead vehicle.
Following requires proximity.
