Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven. Whosoever therefore shall confess me before men - That is, whosoever shall acknowledge me to be the Messiah, and have his heart and life regulated by my spirit and doctrine. It is not merely sufficient to have the heart right before God; there must be a firm, manly, and public profession of Christ before men. "I am no hypocrite," says one; neither should you be. "I will keep my religion to myself" i.e. you will not confess Christ before men; then he will renounce you before God.
We confess or own Christ when we own his doctrine, his ministers, his servants, and when no fear hinders us from supporting and assisting them in times of necessity.
