Frequently Asked Questions

What does it mean to 'wait upon the LORD'?

Waiting on the Lord isn't passive inactivity — it's active trust. The Hebrew word implies eager expectation, like a waiter attending to a master. It means looking to God as your source, trusting His timing, and resting in His promises while continuing to be faithful.

Why does God allow exhaustion?

Exhaustion often reveals misplaced reliance on our own strength. God allows weariness to draw us back to dependence on Him. Isaiah 40:29 specifically says He gives power 'to the faint' — those who have no might. Weakness is the prerequisite for supernatural strength.
