You have asked for renewed strength, and it is a prayer most after God’s own heart, for He delights to give power to the faint and to increase the might of them that have no strength. The promise stands fast: “They that wait upon the LORD shall renew their strength.” It is not a strength drawn from wells of your own digging, but a strength infused by the Spirit of God, wisely balanced, fitly proportioned to the day, and ever glorifying the Giver.
Suffer me to press upon you the very marrow of this truth. When you feel you have no power left, no ability of any kind, then fling yourself upon the divine strength and lay hold upon it. The Lord Himself says, “I will strengthen them.” He does not ask you to muster what you lack; He gives it. Have you no strength even to pray? Cry for life! While you are yet without strength, Christ died for the ungodly. That is your foothold, your weakness is the very platform upon which His omnipotence displays itself.
Think of the eagle. Its youth is renewed not by struggling against the tempest, but by spreading its wings upon the upper air, by feeding upon what God provides, and by breathing the pure atmosphere far above this smoky world. So it is with you. Wait upon God for everything, casting your nothingness upon His all-sufficiency, and your strength shall be renewed. It may come gradually, for recovery is often slow; yet as you grow a little stronger, and a little stronger, acknowledge in each increase that the Lord has a new claim on your affection.
And do not forget the hidden spring of this strength: “The joy of the Lord is your strength.” It is not a forced cheerfulness of your own making, but a deep, quiet joy rooted in the finished work of Christ, the peace that flows from His blood, and the hope of His glory. That joy braces the soul, calms the fevered mind, and makes you strong to endure. When the past rises up in dark memories, and the present feels like a flood, look to the cross. There is your joy, for there your sin and shame were borne. There is your strength, for He who bore them gives you His own Spirit.
Rest in this, then: your strength shall be exactly as your days. Not as your desires, not as your fears, but as the days themselves, measured out by a Father’s hand. A day of overwhelming trial? Thine shall be a Samson’s strength. A day of quiet, hidden pain? Strength sufficient for that quiet valley. The promise is not that you shall escape the robbers in the wood or the lions that roar, but that in every step, His grace shall be enough.
Give to God all the strength you receive, and when you feel renewed, do not use it as though it were your own. Let the glory of your strength lie in God alone, not in any creature, nor in any effort of your own. When you have submitted yourself completely and trusted entirely, setting both your strength and your weakness on one side and yielding yourself for God to use you, then you shall renew your strength. Then go forward to renewed action, leaning upon your Beloved, until the day dawn and the shadows flee away.
Let this be your prayer without ceasing: “O blessed Spirit, awaken me to renewed consecration, renewed zeal, renewed delight in holy service, and renewed hope of victory!” And He who hears the cry of the bruised reed will answer you in the hour of need.
