Where was the door to the sheepfold?
The door to the sheepfold was at ground level. It was not 100 feet up in the air, not down in a cave, and not across a raging river. This physical location illustrates that salvation is also at ground level—accessible by faith, not by human effort or merit.
Les explains that the door to the sheepfold was on ground level, not elevated 100 feet in the air, not down in a cave, and not across a raging river. He then draws the analogy that our salvation is the same: it is always right at ground level. We do not have to climb a high mountain, pay a million dollars, or shape up to earn it. The Holy Spirit has been and is doing His work to bring us to the place where we walk through that door by faith.
