Frequently Asked Questions

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

Waiting on the Lord combines patient trust, active expectation, and continued service. It's like a waiter who 'waits on' a table — attentive, ready to act, focused on the master. It means staying in God's presence, obeying what you know, and trusting His timing for what you don't.

Why does the verse progress from flying to running to walking?

This beautifully captures the full Christian life. Some seasons you soar — experiencing mountaintop victories. Others require sustained running — steady, purposeful effort. And sometimes you're just walking — one foot in front of the other. God promises strength for all three.
