I am not worthy ... - This was an expression of great humility. It refers, doubtless, to his view of his "personal" unworthiness, and not merely to the fact that he was a "Gentile." It was the expression of a conviction of the great dignity and power of the Saviour, and of a feeling that he was so unlike him that he was not suitable that the Son of God should come into his dwelling. So every truly penitent sinner feels - a feeling which is appropriate when he comes to Christ.

But speak the word only - Or instead of ειπε λογον read ειπε λογω, speak by word or command. This reading is supported by the most extensive evidence from MSS., versions, and fathers. See here the pattern of that living faith and genuine humility which ought always to accompany the prayer of a sinner: Jesus can will away the palsy, and speak away the most grievous torments. The first degree of humility is to acknowledge the necessity of God's mercy, and our own inability to help ourselves: the second, to confess the freeness of his grace, and our own utter unworthiness. Ignorance, unbelief, and presumption will ever retard our spiritual cure.

The centurion answered, and said,.... This, according to Luke 7:6 was said by his friends in his name, when he understood that Christ had agreed to come to his house, with the elders of the Jews, he first sent to him; and after he was actually set out with them, and was in the way to his house; who, conscious of his own unworthiness, deputes some persons to him, to address him in this manner,

Lord, I am not worthy that thou shouldst come under my roof. This is not said as rejecting and despising the presence and company of Christ; but is expressive of his great modesty and humility, and of his consciousness of his own vileness, and unworthiness of having so great a person in his house: it was too great a favour for him to enjoy. And if such a man was unworthy, having been an idolater, and lived a profane course of life, that Christ should come into his house, and be, though but for a short time, under his roof; how much more unworthy are poor sinful creatures (and sensible sinners see themselves to be so unworthy), that Christ should come into their hearts, and dwell there by faith, as he does, in all true believers, however vile and sinful they have been?

But speak the word only, and my servant shall be healed. As the former expression declares his modesty and humility, and the mean apprehensions he had of himself; so this signifies his great faith in Christ, and the persuasion he had of his divine power: he does not say pray, and my servant shall be healed, as looking upon him barely as a man of God, a prophet, one that had great interest in God, and at the throne of grace; but speak, command, order it to be done, and it shall be done, which is ascribing omnipotence to him; such power as was put forth in creation, by the all commanding word of God; "he spake, and it was done, he commanded, and it stood fast", Psalm 33:9 yea, he signifies that if he would but speak a word, the least word whatever; or, as Luke has it, "say in a word"; let but a word come out of thy mouth, and it will be done.

The centurion answered and said, Lord, I am not worthy that thou shouldest come under my roof: but speak the word only, and my servant shall be healed.

8:8 The centurion answered. Through friends whom he had sent for this purpose (Lu 7:6).

I am not worthy that thou shouldest come under my roof. This humility was partly due to his consciousness that he was a Gentile. Rigid Jews did not hold social intercourse with Gentiles, and the centurion may have supposed that so holy a Jewish teacher as Jesus would hesitate to come under his roof.

Speak the word only. Speak only a word is the idea, and my servant will be healed. Not even Martha (Joh 11:21) thought that Jesus could have saved her brother Lazarus without going to him. His faith was great.

8:8 The centurion answered - By his second messengers.

8:5-13 This centurion was a heathen, a Roman soldier. Though he was a soldier, yet he was a godly man. No man's calling or place will be an excuse for unbelief and sin. See how he states his servant's case. We should concern ourselves for the souls of our children and servants, who are spiritually sick, who feel not spiritual evils, who know not that which is spiritually good; and we should bring them to Christ by faith and prayers. Observe his self-abasement. Humble souls are made more humble by Christ's gracious dealings with them. Observe his great faith. The more diffident we are of ourselves, the stronger will be our confidence in Christ. Herein the centurion owns him to have Divine power, and a full command of all the creatures and powers of nature, as a master over his servants. Such servants we all should be to God; we must go and come, according to the directions of his word and the disposals of his providence. But when the Son of man comes he finds little faith, therefore he finds little fruit. An outward profession may cause us to be called children of the kingdom; but if we rest in that, and have nothing else to show, we shall be cast out. The servant got a cure of his disease, and the master got the approval of his faith. What was said to him, is said to all, Believe, and ye shall receive; only believe. See the power of Christ, and the power of faith. The healing of our souls is at once the effect and evidence of our interest in the blood of Christ.
