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.
