How very friendly and lovingly the Lord invites all hearts to himself in this example and stirs them to believe in him! There is no doubt that he desires to do for all what he does here for these lepers, if we only freely surrender ourselves to him for all his favor and grace. The Lord desires that we should joyfully and freely venture to build on his favor before we feel or experience it. He has here sufficiently testified that he hears them willingly without any hesitation. He does not first say he will do it, but as though it were already done, he did as they wished. He does not say : I will have mercy on you, and cleanse you; but merely: "Go show yourselves unto the priests." As though he would say: There is no use of asking, your faith has already acquired and obtained it, before you begin to ask; you were already cleansed in my sight when you began to expect such things of me; only go and show yourselves to the priests; as I consider you and as you believe, so you are and shall be. Behold, so powerful is faith to obtain all it wants of God, that God considers it done before the asking.
The lepers have taught us how to believe; Christ teaches us to love. Love does to its neighbor as it sees Christ has done to us. This is a Christian life; it does not need much teaching, or many books, it is wholly contained in faith and love.
