“. . . every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.” Philippians 2:9-11
The most common explanation of this verse is that on Judgment Day God will force every tongue to confess that Jesus Christ is Lord. He’ll be like the emperors in Rome who forced submission from their captives. But God is not a cruel tyrant who forces confessions from His vanquished enemies.
Scripture makes it clear that God does not look kindly on those who honor Him with their lips but not their hearts. Jesus challenged the Pharisees and teachers of the law who came to Him from Jerusalem with these words, “You hypocrites! Isaiah was right when he prophesied about you: ‘These people honor me with their lips, but their hearts are far from me. They worship me in vain … ”
The bowing before Him and confessing that Jesus is Lord is to the glory of God, It is freely given. In fact, every use in the New Testament of the word translated confess in the above verse connotes a voluntary confession.
