…his father saw him, and was moved with compassion, and ran, and fell upon his neck, and covered him with kisses. – Luke 15:20 (DBY)

In the Revised Version, if you will kindly look at the margin, you will find that the text there reads, “And kissed him much.” This is a very good translation of the Greek, which might bear the meaning, “Kissed him earnestly,” or “Kissed him eagerly,” or “Kissed him often.”…God never gives an expression of love without feeling it in His infinite heart. God will never give a Judas-kiss, and betray those whom He embraces. There is no hypocrisy with God; He never kisses those for whom He has no love. Oh, how God loves the sinner! You who repent, and come to Him, will discover how greatly He loves you. There is no measuring the love He bears towards you. He has loved you before the foundation of the world, and He will love you when time shall be no more. Oh, the immeasurable love of God to sinners who come and cast themselves upon His mercy!

This much kissing also means much love manifested. God’s people do not always know the greatness of His love to them. Sometimes, however, it is shed abroad in our hearts by the Holy Ghost which is given unto us. Some of us know at times what it is to be almost too happy to live! …Beloved, God has wondrous ways of opening His people’s hearts to the manifestation of His grace. He can pour in, not now and then a drop of His love, but great and mighty streams. Madame Guyon used to speak of the torrents of love that come sweeping through the spirit, bearing all before them. The poor prodigal in the parable had so much love manifested to him, that he might have sung of the torrents of his father’s affection. That is the way God receives those whom He saves, giving them not a meager measure of grace, but manifesting an overflowing love. ~ C.H. Spurgeon
