The custom was to kiss the statues to show honor and reverence. Hosea shows the foolishness and ignorance of such idol worship. He says that the idols are the work of man's hands. They can be explained by human understanding. Christians today would not dare bow their knee to Baal or stoop to kiss an ancient idol.
Idolatry lives today in the hearts of men as much as ever before.
Our idols today are sports gods, money gods, entertainment gods, or political gods. Let it not be so in our lives. And while he was yet speaking, behold a multitude, and he that was called Judas, one of the twelve, went before them, and drew near to Jesus to kiss him. This is without doubt one of the most despicable passages of scripture in the entire Word of God. Judas' kiss was not only to identify Jesus, but a blatant attempt to fool Christ into thinking that he was innocent.
