“I will walk in mine integrity,” was David’s staff, and in doing anything there is no such guide to do it well as the integrity of the heart. Knowledge is requisite, and is a good director: counsel may be needful, and is a good conductor; but the master pilot is the sincerity of the heart. If that be wanting the others will not be following, if that be present the others will not be wanting.—Jermin.

Everyone that is truly godly hath a faithful guide and an upright counsellor in his own breast. A sound heart is the stern of the soul, and a good conscience is the pilot to govern it.—Dod.

A man, to be led, must have a way; and, to have a way, he must have an end at which he is aiming. The end of the “upright” man is righteousness itself. If the great joy of heaven is uprightness, and the price of wisdom is above rubies, of course “integrity” is the best guide in the world, because of course righteousness is the best guide to righteousness; and, poor or rich, the righteous man is always advancing in his treasure. Righteousness is also the best guide to happiness, for no good thing shall be withholden from them that walk uprightly. Sin, on the other hand, by increasing itself, is itself its own seducer.—Miller.

Sincerity is one eminent branch of the good man’s character. Nathaniel was a man without guile. We accordingly find that, though prejudiced against Jesus of Nazareth, his sincerity appeared in the means which he employed to arrive at a knowledge of the truth, and he was led by it in the right way. Christ’s enemies were men of perverse spirits. They crucified Him with a view to maintain their honour and preserve their nation; but by their perverse conduct both were destroyed.—Lawson.

Every man who comes into a state of right intent, will forthwith also be a Christian. Whoever is willing to be carried just where it will carry him, cost him what it may, in that man the spirit of all sin is broken, and his mind is in a state to lay hold of Christ and to be laid hold of by Him. . . . “For the eyes of the Lord run to and fro throughout the whole earth, to show Himself strong in the behalf of them whose heart is perfect toward Him” (2 Chron. xvi. 9). God is on the lookout always for an honest man—him to help, and with him, and for him, to be strong. And if there be one, God will not miss him; for His desiring, all-searching eyes are running the world through always to find him.—Bushnell.

I. The guidance of integrity is the safest under which we can be placed. Perfect immunity from danger is not to be expected in this life. But let us inquire who the persons are that, in all the different lines of life, have gone through the world with most success, and we shall find that the men of probity and honour form by far the most considerable part of the list; that men of plain understanding, acting upon fair and direct views, have much oftener prospered than men of the deepest policy, who were devoid of principle. II. It is unquestionably the most honourable. Other qualities may add splendour to character; but if this essential requisite be wanting, all its lustre fades. He who rests upon an internal principle of virtue and honour, will act with a dignity and boldness of which they are incapable who are wholly guided by interest. He is above those timid, suspicious, and cautious restraints which fetter and embarrass their conduct. III. This plan of conduct is the most comfortable. Amidst the various and perplexing events of life, it is of singular advantage to be kept free from doubt as to the part most proper to be chosen. The man of principle is a stranger to those inward troubles which beset men who consult nothing but worldly interest. His time is not lost, nor his temper fretted, by long and anxious consultations. One light always shines upon him from above. One path always opens clear and distinct upon his view. He is also delivered from all inward upbraidings, from all alarms founded on the dread of discovery and disgrace. The man of virtue has committed his way to the Lord. He co-operates with the Divine purpose. The power which sways the universe is engaged on his side. By natural consequence, he has ground to expect that any seeming disappointments which he may now incur shall be over-ruled in the end to some salutary result. IV. He has always in view the prospect of immortal rewards. That surely is the wisest direction of conduct, which is most amply recompensed at last.—Blair.
