To such favored saints Jude wishes his gracious apostolic benediction of mercy, peace, and love.  By mercy he intends the continual outflow of God’s kind protection and assistance in all the trials and hardships of this earthly life.  Believers are a people beset with all the common trials familiar to mankind, and also many difficulties to which the world is immune.  In the midst of persecution and attacks upon the faith, Jude prays that God would continue to favor His chosen people with fresh discoveries of His mercy, so that they would know that they are not alone in the midst of the furnace of affliction.

Peace also is wished upon the saints.  Peace externally in the world is a wonderful gift, but the word of Christ is that in the world we shall have tribulation.  Periods of peace are few and far between, and much to be cherished by those pursuing the Christian pilgrimage.  But spiritual peace is something which even the most sorely tried Christian may enjoy, through the blessing of God upon him.  The knowledge of sins forgiven, the joy of communion with God, the sweet fruits of the Gospel, will work within him a peace which the world cannot give nor understand.  The highest earthly joys and accomplishments soon vanish away, leaving the participants hungering for something new and fresh.  But the joy that comes through a knowledge of Christ as Saviour produces a peace that neither men nor devils can steal from us.  It must be acknowledged that when we become bogged down in the hardships of daily living, our delight in the Gospel may waver.  Jude’s prayer for peace is a very necessary one, for when our view of the Gospel is diminished, our peace will decrease in corresponding degree.

Jude prays also for a multiplication of love to those sanctified in God the Father and preserved in Jesus Christ.  This may be understood two ways; I say not, in one of two ways, for I think it fully tenable to accept that the apostle intends both.  We may think of it as Jude praying for an increase of the love of God to be shed abroad in the hearts of the saints by the Holy Ghost.  This is a most sweet and necessary grace, which greatly strengthens believers to run in the ways of the Lord.  We are daily in need of fresh discoveries of the saving love of Christ, the tender love of the Father, and the grace of the Spirit within us.  When we lose sight of the fact that our God pities us even as a father pitieth his children, then our soul may be much discouraged by the way.  The manifestation of the love of God in the hearts of His children is a very strengthening and encouraging grace, for which all ought to constantly pray.

We could also understand it as a prayer for the multiplication of mutual love between the brethren.  This also is a very necessary grace, for it is all too easy for those still affected by sin to grow disenchanted with one another, and to become very disagreeable.  Part of Satan’s unrelenting warfare is to stir up strife in the churches of God.  Thus, the apostles were always quick to admonish the churches to walk in love, and also to pray that their love may be increased.  Jude, I think, prays both for the love of God, and for an increase of love between the brethren, in this apostolic benediction.
