It is faith, practical faith, which has been urged, faith exercised in energetic prayer. The Epistle does not close without an earnest pressure of love in a similarly active way, and indeed in manifest connection.
“My brethren, if any among you should err from the truth, and one turn him back, let him know that he that turneth back a sinner from the error of his way shall save a [or, his] soul from death, and shall cover a multitude of sins” (vers. 19, 20).
One of the saddest results of spiritual weakness among Christians is the rarity of restoration. Discipline even in extreme degree is no less due to our Lord, to our sacrificed Lord (1 Cor. 5:7, 87Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us: 8Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth. (1 Corinthians 5:7‑8)), than requisite in the best interests of the saints. For true love of our brethren is inseparable from loving God and keeping His commandments (1 John 5:1, 21Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him. 2By this we know that we love the children of God, when we love God, and keep his commandments. (1 John 5:1‑2)). But our God attests often and clearly and strongly His deep concern in the recovery of the straying and fallen; where self-righteousness displays its bitterness and indifference. Zeal for the credit of a sect or party and anxiety to stand well morally are as far as possible from the love we owe to Christ's body and every member of it.
For we are exhorted to forgive (or, show grace to) one another, as God also in Christ forgave us (Eph. 4:3232And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you. (Ephesians 4:32)); yea to be imitators of God, as beloved children, and to walk in love, even as Christ loved us and gave Himself up for us. But this love divine is meant to arm us against fellowship with the ways of darkness, seeing that we are light in the Lord to walk as children of light, the fruit of which is in all goodness, and righteousness, and truth (Eph. 5:7-97Be not ye therefore partakers with them. 8For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light: 9(For the fruit of the Spirit is in all goodness and righteousness and truth;) (Ephesians 5:7‑9)). Hence the spiritual in a spirit of meekness are to restore one taken in some fault, “considering thyself lest thou also be tempted.” Hardness is unworthy of a Christian. “If thy brother sin, rebuke him; and if he repent, forgive him. And if he should sin against thee seven times in the day, and seven times return to thee, saying, I repent, thou shalt forgive him” (Luke 17:3, 43Take heed to yourselves: If thy brother trespass against thee, rebuke him; and if he repent, forgive him. 4And if he trespass against thee seven times in a day, and seven times in a day turn again to thee, saying, I repent; thou shalt forgive him. (Luke 17:3‑4)).
So here, if one brought back him that erred or was led astray from the truth, let him know that in such a recovery he that brought him back from his way of error should “save a soul from death.” Here it is not a striking answer to the prayer of faith, but a rich cheer to the love that sought and won the wanderer. To have the sick healed and raised up as the fruit of prayer may strike the eye more; but how blessed to “save a soul from death”! Thus would our God encourage a spirit of grace in the thankful knowledge that love has its victories in a world of self and hatred and evil; and this, not only in regard of him that erred from the truth and its way, but in furnishing occasion, for that which is so pleasing to God in His government-to “cover a multitude of sins.” If love do not flow, wrongs multiply, and God chastens, it may be severely; for where is Christ in such a case? But if love prevail through His grace, God is glorified, and love covers a multitude of sins, which otherwise must draw out His rebukes.
