Summon your power, O God,
the power, O God, by which you have worked for us.
It is wise, as well as necessary, to ask God continually to strengthen what He has worked in us. Failure to do so finds many Christians blaming themselves for those trials and afflictions of spirit that arise from unbelief. It is true that Satan seeks to flood the fair garden of the heart and make it a scene of desolation, but it is also true that many Christians leave open the floodgates themselves and let in the dreadful deluge as a result of carelessness and lack of prayer to their strong Helper.
We often forget that the Author of our faith must be the Preserver of it also. The lamp that was burning in the temple was never allowed to go out, but it had to be replenished every day with fresh oil; in the same way, our faith can only live by being sustained with the oil of grace, and we can only obtain this from God Himself. We will fail if we do not secure the needed sustenance for our lamps. He who built the world upholds it, or it would fall in one tremendous crash. He who made us Christians must maintain us by His Spirit, or our ruin will be speedy and final.
So let us, then, evening by evening, go to our Lord for the grace and strength we need. We have a strong argument to plead, for it is His own work of grace that we ask Him to strengthen—"the power . . . by which you have worked for us." Do you think He will fail to protect and provide that? Let your faith simply take hold of His strength, and all the powers of darkness, led by the master fiend of hell, cannot cast a cloud or shadow over your joy and peace. Why faint when you can be strong? Why suffer defeat when you may conquer? Take your wavering faith and faltering graces to Him who can revive and replenish them, and earnestly pray, "Summon your power, O God . . . by which you have worked for us."
