The Christian walk requires endurance. God will use trials and tribulations to build our faith. The famous runner Jim Ryun, who set a mile record when he was eighteen years old, talked about his training:

“I would run until I felt I couldn’t take another step; then I would run until I felt my lungs were going to burst. When I came to that state, then I would run until I thought I was going to pass out. When I did this, I was making progress.”
