…and covered him with kisses. – Luke 15:20

There stood the prodigal, overwhelmed by his father’s goodness, yet remembering his past life. As he looked on himself, and thought, “I have these old rags on still, and I have just come from feeding the swine,” I can imagine that his father would give him another kiss, as much as to say, “My boy, I do not recollect the past; I am so glad to see you that I do not see any filth on you, or any rags on you either. I am so delighted to have you with me once more that, as I would pick up a diamond out of the mire, and be glad to get the diamond again, so do I pick you up, you are so precious to me.” This is the gracious and glorious way in which God treats those who return to Him. As for their sin, He has put it away so that He will not remember it. Well may we adore and magnify His matchless mercy as we sing-

“In wonder lost, with trembling joy
We take the pardon of our God;
Pardon for crimes of deepest dye;
A pardon bought with Jesus’ blood;
Who is a pardoning God like Thee?
Or who has grace so rich and free?”

“Well,” says one, “can such a wonderful change ever take place with me?” By the grace of God it may be experienced by every man who is willing to return to God. I pray God that it may happen now, and that you may get such assurance of it from the Word of God, by the power of His Holy Spirit, and from a sight of the precious blood of Christ shed for your redemption, that you may be able to say, “I understand it now; I see how He kisses all my sin away; and when it rises, He kisses it away again; and when I think of it with shame, He gives me another kiss; and when I blush all over at the remembrance of my evil deeds, He kisses me again and again, to assure me that I am fully and freely forgiven.” Thus the many kisses from the prodigal’s father combined to make his wayward son feel that his sin was indeed all gone. They revealed much love and much forgiveness. ~ C.H. Spurgeon
