Isaiah 40:29
He giveth power to the faint; and to them that have no might he increaseth strength.
Isaiah 40:29
This verse offers a hopeful promise: God gives power to the faint and strengthens the weak. It sits as a compassionate counterpoint to the earlier warnings against idolatry and the assertion of God’s unending strength. God’s generosity toward the weary is a hallmark of His merciful character, meeting people where they are in their weakness.
It highlights divine empowerment as a central aspect of comforing faith. Theological themes include God’s grace in strengthening, encouragement of perseverance, and the reality that human weakness becomes an avenue for God’s power to be shown. Paul later cites similar language to describe Christ’s sufficiency in weakness (2 Corinthians 12:9-10), showing continuity in the biblical witness.
In everyday life, this verse invites practical reliance on God in moments of exhaustion—physical, emotional, or spiritual. When you feel drained, pause to pray for renewed strength, seek help from others, and rest in the truth that God is at work strengthening you. For parents, students, and workers, this is a call to pace life with dependence on God’s energy rather than heroic self-sufficiency. It also motivates you to support others who are weak, offering encouragement and tangible help.
