1 John 1:9 (R. V.)—"If we confess our sins, he is faithful and righteous to forgive us our sins, and to cleanse us from all unrighteousness." Ordinarily, the forgiveness of sin is associated with the mercy, love, and compassion of God, and not with His righteousness and justice. This verse assures us that if we confess our sins, the righteousness and justice of God is our guarantee for forgiveness—God cannot but forgive and cleanse us from all sin.
cc) In keeping His word and promise to His children.
Neh. 9:7, 8—"Thou art the Lord the God, who didst choose Abram…and madest a covenant with him to give the land of the Canaanites…to his seed, and hast performed thy words; for thou art righteous." We need to recall the tremendous obstacles which stood in the way of the fulfillment of this promise, and yet we should remember the eleventh chapter of Hebrews. When God gives His word, and makes a promise, naught in heaven, on earth, or in hell can make that promise void. His righteousness is the guarantee of its fulfillment.
dd) In showing Himself to be the vindicator of His people from all their enemies.
Psa. 129:1-4—"Many a time have they afflicted me…yet they have not prevailed against me. The Lord is righteous: he hath cut asunder the cords of the wicked." Sooner or later, God's people will triumph gloriously as David triumphed over Saul. Even in this life God will give us rest from our enemies; and there shall assuredly come a day when we shall be "where the wicked cease from troubling, and the weary are at rest."
ee) In the rewarding of the righteous.
Heb. 6:10—"For God is not unrighteous to forget your work and labor of love, which ye have showed towards his name, in that ye have ministered unto the saints, and do minister." Those who had shown their faith by their works would not now be allowed to lose that faith. The very idea of divine justice implies that the use of this grace, thus evidenced, will be rewarded, not only by continuance in grace, but their final perseverance and reward. 2 Tim. 4:8—"Henceforth there is laid up for me a crown of righteousness, which the Lord, the righteous judge, will give me at that day: and not to me only, but unto all them that love hiss appearing." The righteous Judge will not allow the faithful believer to go unrewarded. He is not like the unrighteous judges of Rome and the Athenian games. Here we are not always rewarded, but some time we shall receive full reward for all the good that we have done. The righteousness of God is the guarantee of all this.
c) The Mercy and Loving-kindness of God.
By these attributes is meant, in general, the kindness, goodness, and compassion of God, the love of God in its relation to both the obedient and the disobedient sons of men. The dew drops on the thistle as well as on the rose.
More specifically: Mercy is usually exercised in connection with guilt; it is that attribute of God which leads Him to seek the welfare, both temporal and spiritual, of sinners, even though at the cost of great sacrifice on His part. "But God, who is rich in mercy, for his great love wherewith he loved us…God commendeth his love towards us, in that, while we were yet sinners, Christ died for us." (Eph. 2:4; Rom. 5:8.)
