Solomon saith, Prov. x. 9, "He that walketh uprightly walketh surely." And perfection and uprightness are the characters of Job, Job i. 1, 8; ii. 3. And in the Scripture to be upright or righteous, and to walk uprightly, and to do righteously, are the titles of those that are acceptable to God. And by uprightness is meant not only sincerity as opposed to hypocrisy; but also rectitude of heart and life, as opposed to crookedness or sin; and this as it is found in various degrees: of which we use to call the lowest degree that is saving by the name of sincerity, and the highest by the name of perfection.
Concerning uprightness of life, I shall, I. Briefly tell you some of those blessings that should make us all in love with it, and, II. Give you some necessary rules of practice.
1. Uprightness of heart and life is a certain fruit of the Spirit of grace, and consequently a mark of our union with Christ, and a proof of our acceptableness with God. "My defence is of God, who saveth the upright in heart," Psal. vii. 10. "For the righteous Lord loveth righteousness, and his countenance doth behold the upright," Psal. xi. 7. It is a title that God himself assumeth; "Good and upright is the Lord," Psal. xxv. 8. "To show that the Lord is upright, he is my Rock, and no unrighteousness is in him," Psal. xcii. 15. And God calleth himself the Maker, the Director, the Protector, and the Lover of the upright. "God made man upright," Eccl. vii. 29. "The Lord knoweth the way of the righteous," Psal. i. 6. "What man is he that feareth the Lord? him will he teach in the way that he shall choose," Psal. xxv. 12. "He layeth up sound wisdom for the righteous; he is a buckler to them that walk uprightly," Prov. ii. 7.
2. The upright are the pillars of human society, that keep up truth and justice in the world: without whom it would be but a company of liars, deceivers, robbers, and enemies, that live in constant rapine and hostility. There were no trust to be put in one another, further than self-interest did oblige men. "Lord, who shall abide in thy tabernacle? Who shall dwell in thy holy hill? He that walketh uprightly, and worketh righteousness, and speaketh the truth in his heart," Psal. xv. 1, 2. Therefore the wicked, and the enemies of peace, and destroyers of societies, are still described as enemies to the upright. "For lo, the wicked bend their bow, they make ready their arrow upon the string, that they may privily shoot at the upright in heart. If the foundations be destroyed, what can the righteous do?" Psal. xi. 2, 3. "The just and upright man is laughed to scorn," Job xii. 4. "The wicked have drawn out the sword to slay such as be of upright conversation," Psal. xxxvii. 14. And indeed it is for the upright's sake that societies are preserved by God, as Sodom might have been for ten Lots. At least they are under the protection of omnipotency themselves. "He that walketh righteously and speaketh uprightly, he that despiseth the gain of oppression, that shaketh his hand from holding of bribes, that stoppeth his ear from hearing of blood, that shutteth his eyes from seeing evil; he shall dwell on high, his place of defence shall be the munitions of rocks: bread shall be given him; his waters shall be sure. Thine eyes shall see the king in his beauty: they shall behold the land that is very far off," Isa. xxxiii. 15, 16. "The upright shall have good things in possession," Prov. xxviii. 10. "The house of the wicked shall be overthrown; but the tabernacle of the upright shall flourish," Prov. xiv. 11.
3. Uprightness affordeth peace of conscience, and quietness and holy security to the soul. This was Paul's rejoicing, the testimony of his conscience, that "in simplicity and godly sincerity he had had his conversation in the world, and not in fleshly wisdom," 2 Cor. i. 12. And this was David's comfort: "For I have kept the ways of the Lord, and have not wickedly departed from my God; for all his judgments were before me, and as for his statutes, I did not depart from them. I was also upright before him, and have kept myself from mine iniquity. Therefore hath the Lord recompensed me according to my righteousness;--with the merciful thou wilt show thyself merciful, and with the upright thou wilt show thyself upright," 2 Sam. xxii. 22-24. Yea, peace is too little; exceeding joy is the portion, and most beseeming condition of the upright. "Be glad in the Lord, and rejoice, ye righteous, and shout for joy, all ye that are upright in heart," Psal. xxxii. 11. "Rejoice in the Lord, O ye righteous, for praise is comely for the upright," Psal. xxxiii. 1. "The righteous shall be glad in the Lord, and trust in him, and all the upright in heart shall glory," Psal. lxiv. 10. "Light is sown for the righteous, and gladness for the upright in heart," Psal. xcvii. 11. The Spirit that sanctifieth them, will comfort them.
