It’s supposed to be tough.
Why do you think God has to call people into this work? If it were easy, they’d be lining up to volunteer.
The Christian life is tough to start with. “In this world you will have tribulations,” our Lord said. Then, He added, “But be of good cheer; I have overcome the world” (John 16:33).
Then, the Lord calls certain ones of the redeemed to stand apart from the flock and to become “point men.” His undershepherds. Overseers of the flock. Examples to the rest. And frequently, His spokesmen.
Targets. In the crosshairs of the enemy.
