But when Simon Peter saw it, he fell down on his knees before Jesus and said: Lord, go away from me, for I am a sinful man! – Luke 5.8
If the Lord will live in a person’s heart, He first must crush it. And the hearts which He will use in His work, He will crush the most thoroughly.
It was not only Peter who recognized the terror in his heart. If the Lord will make us useful, we must be able to see our sin, and seeing sin breeds terror. We must look so deeply at our own heart, our own god-fearing, our own Christian work, such that it becomes our despair. If we shall receive “the wisdom which comes from God,” we must first see our own stupidity.
Therefore, do not become discouraged, my dear co-laborers, when you experience this crushing blow from the Lord. You think that everything is impossible, but nothing is as impossible as you doing something righteous in God’s kingdom.
You think that you are unworthy? Yes, but who is worthy? No one. It is only through grace that we become co-laborers in the Lord’s work. As long as you realize this, it will go well with your labors.
You realize that you’re ill-fitted for the work? Good. As long as you realize it, the Lord can use it. For there is nothing which can make you fitted that you don’t receive from God, and He gives grace to the humble.
No one is so well-suited to win over people as a humble person. A humble person never takes a high position among the believers. A humble person never sows splits and disagreements in the Lord’s flock. And a humble person has an entrance into the heart and conscience of the unconverted that nobody else has.
