You can be still because He is active.
You can rest because He is busy…
To wait, biblically speaking, is not to assume the worst, worry, fret, make demands, or take control. Nor is waiting inactivity. It is a sustained effort to stay focused on God through prayer and belief. To wait is to “rest in the Lord, and wait patiently for Him;… not fret” (Psalm 37:7).
Those who wait on the Lord shall renew their strength; They shall mount up with wings like eagles, they shall run and not be weary, they shall walk and not faint. — Isaiah 40:31
Fresh strength. Renewed vigor. Legs that don’t grow weary.
Delight yourself in God, and He will bring rest to your soul.
