“Out of weakness were made strong.”-Hebrews 11:34.

Brethren, as believers in the Lord Jesus, we are called to two things, namely, to do and to suffer for His name’s sake. Certain saints are summoned to active marching duty, and others are ordered to keep watch on the walls. There are warriors on the field of conflict, and sentries in the box of patience.

Both in doing and in suffering, if we are earnest and observant, we soon discover our own weakness. “Weakness” is all we possess. “Weakness” meets us everywhere. If we have to work for the Lord, we are soon compelled to cry, “Who is sufficient for these things?” and if we are called to suffer for Him, our weakness, in the case of most of us, is even greater: many who can labor without weariness cannot suffer without impatience. Men are seldom equally skilled in the use of the two hands of doing and bearing. Patience is a grace which is rarer and harder to come at than activity and zeal. It is one of the choicest fruits of the Spirit, and is seldom found on newly-planted trees. The fact soon comes home to us that we are weak where we most of all desire to be strong.

Our longing is to be able both to do and to suffer for our Lord, and to do this we must have strength from above, and that strength can only come to us through faith. (Read you this glorious 11th chapter of Hebrews), which describes the mighty men of faith, the men of renown. They accomplished all their feats by a power which was not in them by nature. They were not naturally strong either to do or to suffer. If they had been, they would not have required faith in God; but being men of like passions with ourselves, they needed to trust in the Lord, and they did so. They were quite as weak as the weakest of us; but by their faith they laid hold on heavenly strength until they could do all things. There was nothing in the range of possibility, or, I might say, nothing within the lines of impossibility, which they could not have performed. They achieved everything that was necessary in the form of service, and they bore up gloriously under the most fearful pressure of suffering, simply and only by faith in God, who became their Helper. You and I may be very weak at this time, but we can be made strong out of just such weakness. We need not wish to have any strength of our own, for by faith we can reach to any degree of power in the Lord. We can have all imaginable strength for the grandest achievements desirable, if we have faith in God. ~ C.H. Spurgeon
