Whosoever he be of you - This seems to be addressed particularly to those who were then, and who were to be, preachers of his Gospel; and who were to travel over all countries, publishing salvation to a lost world.

So likewise whosoever he be of you,.... Let him be ever so forward to follow me, to make a profession of me and of my Gospel, and to become a disciple of mine:

that forsaketh not all that he hath; when called to it, relations, friends, possessions, estates, and what not, which is an explanation of Luke 14:26

he cannot be my disciple; he is not in fact one, and is not worthy to be called one.

Forsaketh (ἀποτάσσεται)

Bids good-by to. Rev., renounceth. See on Luke 9:61. "In that forsaketh lies the key to the whole passage" (Trench). Christian discipleship is founded in self-renunciation.

So likewise, whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple.

14:28-33 Sitteth not down first, and counteth the cost? This calculation of what any enterprise or step will require before entering upon it is the part of wisdom. So, too, a disciple of Christ should count the cost. It is well to understand that every obstacle to the service of Christ must be given up.

14:33 So - Like this man, who, being afraid to face his enemy, sends to make peace with him, every one who forsaketh not all that he hath - By withdrawing his affections from all the creatures; By enjoying them only in and for God, only in such a measure and manner as leads to him; By hating them all, in the sense above mentioned, cannot be my disciple - But will surely desist from building that tower, neither can he persevere in fighting the good fight of faith.

14:25-35 Though the disciples of Christ are not all crucified, yet they all bear their cross, and must bear it in the way of duty. Jesus bids them count upon it, and then consider of it. Our Saviour explains this by two similitudes; the former showing that we must consider the expenses of our religion; the latter, that we must consider the perils of it. Sit down and count the cost; consider it will cost the mortifying of sin, even the most beloved lusts. The proudest and most daring sinner cannot stand against God, for who knows the power of his anger? It is our interest to seek peace with him, and we need not send to ask conditions of peace, they are offered to us, and are highly to our advantage. In some way a disciple of Christ will be put to the trial. May we seek to be disciples indeed, and be careful not to grow slack in our profession, or afraid of the cross; that we may be the good salt of the earth, to season those around us with the savour of Christ.
