And Jesus said unto him, No man, having put his hand to the plough, and looking back, is fit for the kingdom of God.

People's New Testament

9:62 No man, having put his hand to the plough. An agricultural figure. The plowman must look ahead instead of back. So, too, of the Christian. The Savior's words were suggested by a request of one to go home for a farewell before following him. In thousands of instances it has been show that the convert who goes to confer with unbelieving relatives before the final step is likely to part with Christ instead. Heathen, ready to be baptized, who go home for a final farewell before the step, are likely to be persuaded not to take it, so missionaries tell us.

Wesley's Notes

9:62 Is fit for the kingdom of God - Either to propagate or to receive it.

Jamieson-Fausset-Brown Bible Commentary

62. No man, &c.-As ploughing requires an eye intent on the furrow to be made, and is marred the instant one turns about, so will they come short of salvation who prosecute the work of God with a distracted attention, a divided heart. Though the reference seems chiefly to ministers, the application is general. The expression "looking back" has a manifest reference to "Lot's wife" (Ge 19:26; and see on [1621]Lu 17:32). It is not actual return to the world, but a reluctance to break with it. (Also see on [1622]Mt 8:21.)

Matthew Henry's Concise Commentary

9:57-62 Here is one that is forward to follow Christ, but seems to have been hasty and rash, and not to have counted the cost. If we mean to follow Christ, we must lay aside the thoughts of great things in the world. Let us not try to join the profession of Christianity, with seeking after worldly advantages. Here is another that seems resolved to follow Christ, but he begs a short delay. To this man Christ first gave the call; he said to him, Follow me. Religion teaches us to be kind and good, to show piety at home, and to requite our parents; but we must not make these an excuse for neglecting our duty to God. Here is another that is willing to follow Christ, but he must have a little time to talk with his friends about it, and to set in order his household affairs, and give directions concerning them. He seemed to have worldly concerns more upon his heart than he ought to have, and he was willing to enter into a temptation leading him from his purpose of following Christ. No one can do any business in a proper manner, if he is attending to other things. Those who begin with the work of God, must resolve to go on, or they will make nothing of it. Looking back, leads to drawing back, and drawing back is to perdition. He only that endures to the end shall be saved.
