Matteo 7:21

False discipleship: Not everyone that saith unto Me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of My Father which is in heaven.

False teachers have been characterized, spurious disciples are here described. Not all of those that make a practice of public confession are in truth confessors. They may try to cover their hypocrisy by publicly acknowledging and professing Jesus as the Lord, thus apparently giving Him divine honor and glory, which is implied in this appellation. But a mouth-Christianity can never be a valid substitute for heart-Christianity.

The fact that the lips readily form the name of Christ the Lord, make a practice of repeating it, will bring no one into the kingdom of heaven nor let him enter into the blessed communion of those that are one with Christ. Even a mere listening to His teaching with admiration and appreciation will avail nothing. But among those that profess Christ there are also others, such as have received Christ in faith and have by Him been renewed in heart and mind.

They receive spiritual power from Him continually and are thus enabled to carry out the will of the heavenly Father in their lives. The performing of the will of God thus becomes the criterion by which the sincerity of their discipleship is tested. Christ calls God "My Father. " In His deep humility He is not seeking His own glory. He has the right to bear the name Lord and to demand obedience to His will. But He impresses upon His hearers the sacredness of the revealed will of God; that should find expression in their lives.
