Isaiah 40:31 Meaning: Renewed Strength for Those Who Wait

The Hebrew word for wait here is qavah. It means to wait with intense expectancy, like a servant scanning the horizon for the master’s return. The old commentators pictured it as the twisting of a cord, several strands woven together into something strong. Waiting on God is not killing time; it is actively hoping, turning your face toward Him again and again.

The verb for renew is chalaph, which means to exchange or change for the better. It is the word used when a worn-out garment is replaced with a new one. The strength God gives does not just patch up the old, He trades it for something fresh. And mount up with wings uses ever, a poetic word for pinion, the strong feather that lifts a bird. The picture is not of flapping frantically but of being carried by a power beyond your own.

Christians have read this verse in different ways. Some, following an old legend, see the eagle renewal as a promise that God will restore youth and vitality, like the moulting eagle that grows fresh feathers. Others focus on the eagle’s ability to soar high above trouble, suggesting that waiting on God lifts us above our circumstances. Calvin highlighted patience: waiting means not rushing ahead but resting in God’s timing, knowing that strength comes through stillness. The Anglican commentator in the Cambridge Bible thought the main point was the new quality of life the believer receives, borne aloft on wings of faith and hope. All traditions agree that the source of the strength is God alone, and the waiting itself is active trust.

A common mistake is to think that “waiting on the Lord” means doing nothing, passively sitting around until God acts. In fact, the Hebrew word qavah is alive with expectation. It is the posture of a lookout who keeps watching, a servant who stands ready. You can be busy with daily duties and still be waiting on God, because waiting is an orientation of the heart, not a lack of motion.

This week, think about one area where you feel depleted, a long illness, a prayer that seems unanswered, a relationship that drains you. Instead of pushing harder or giving up, try a different pace. Set aside a few minutes each day to turn that particular weariness over to God. Say to Him, “I am waiting for You.” That is not passive; it is a choice to trade your exhaustion for His supply. The promise is that He will exchange your worn-out strength for new. You might not feel a sudden rush of energy, but over days you will notice a quiet sustaining power underneath your steps.
