To appoint unto them that mourn in Zion, to give unto them beauty for ashes, the oil of joy for mourning, the garment of praise for the spirit of heaviness; that they might be called trees of righteousness, the planting of the Lord, that He might be glorified. Isaiah 61:3. RRe 116.1
While we sorrow on account of sin, we are to rejoice in the precious privilege of being children of God. RRe 116.2
We often sorrow because our evil deeds bring unpleasant consequences to ourselves; but this is not repentance. Real sorrow for sin is the result of the working of the Holy Spirit. The Spirit reveals the ingratitude of the heart that has slighted and grieved the Saviour, and brings us in contrition to the foot of the cross. By every sin, Jesus is wounded afresh; and as we look upon Him whom we have pierced, we mourn for the sins that have brought anguish upon Him. Such mourning will lead to the renunciation of sin.... RRe 116.3
The tears of the penitent are only the rain-drops that precede the sunshine of holiness. This sorrow heralds a joy which will be a living fountain in the soul. “Only acknowledge thine iniquity, that thou has transgressed against the Lord thy God”; “and I will not cause Mine anger to fall upon you; for I am merciful, saith the Lord.” “Unto them that mourn in Zion,” He has appointed to give “beauty for ashes, the oil of joy for mourning, the garment of praise for the spirit of heaviness.”—The Desire of Ages, 300.
