The Master has now said everything necessary in order to clear away popular misapprehensions, and place the truth about His kingdom fairly before the minds of His hearers. He has explained its nature as inward and spiritual, setting forth the character of those who belong to it, the blessedness they will enjoy, and the influence they will exert on the world around them. He has set forth clearly and fully the obligations that will rest upon them, as summed up in the comprehensive requirement of righteousness understood in a larger and deeper sense than ever before--obligations of such stringency as to make it apparent that to seek the kingdom of God and His righteousness is no holiday undertaking, that it is no easy thing to be a Christian, but that it requires self-restraint, self-humbling, self-denial; and that therefore His kingdom cannot be attractive to the many, but must appeal to those who are earnest-spirited enough to ask and seek and knock for admittance. Now that all has been fully and faithfully set forth--now that there is no danger of obtaining disciples under misapprehension--the great invitation is issued: _Enter ye in_. It is the free universal invitation of the Gospel, as large and liberal as that later one, "Whosoever will, let him come," though given in such a way as to keep still prominently before the minds of all comers what they may expect, and what is expected of them: "Enter ye in by the narrow gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many be they that enter in thereby. For narrow is the gate, and straitened the way, that leadeth unto life, and few be they that find it" (R.V.).
