Even some who acknowledge Christ as Teacher and Savior will be excluded from the kingdom of Heaven, having never been a true subject of the kingdom of grace. Only those who actually do the Fathers will shall be finally and eternally saved. A person can desire to be accounted a Christian and be accepted among the people as a follower of Christ, and yet have no real love for Christ or His cause. The obedience here required is not mere outward obedience of the law of God, nor is it a bare subjection to the ordinances of the gospel. It is faith in Christ for life and salvation which is the source of all true obedience and without which nothing is acceptable to God.
Profession is no substitute for obedience.
Because of faith in Him and love for Him we must do what He requires and obey His commandments. Let no man imagine that he builds on the tried Foundation who hears the words of Christ and does not obey them. It surely means in the day of judgment when men stand before Christ, the righteous Judge of all the earth. This text makes it plain that Jesus Christ laid claim to being the judge of the living and the dead. He is the future Judge of the world.
