Matthew 5:4 KJV, “Blessed are they that mourn: for they shall be comforted.”
Ecclesiastes 7:2-3 KJV, “It is better to go to the house of mourning, than to go to the house of feasting: for that is the end of all men; and the living will lay it to his heart. Sorrow is better than laughter: for by the sadness of the countenance the heart is made better.”
EG White, SOP Vol 2, 1877, Pp. 205-206, “In pronouncing a blessing upon those who mourn, Jesus did not design to teach that there is any virtue in living under a perpetual cloud, nor that selfish sorrow and repining has any merit of itself to remove a single stain of sin. The mourning spoken of by Christ is a godly sorrow for sin, that works repentance unto eternal life. Many grieve when their guilt is discovered, because the result of their evil course has brought them into disagreeable circumstances. It was thus that Esau mourned the sin of despising and selling his birth-right; but it was the unexpected consequences of that sin which caused his grief. So Pharaoh regretted his stubborn defiance of God, when he cried for the plagues to be removed from him; but his heart was unchanged, and he was ready to repeat his crime when tempted. Such mourning is not unto repentance.”
“He who is truly convicted of sin feels his whole life to have been one continued scene of ingratitude. He feels that he has robbed his best friend of the time and strength which was bought for him at an infinite price. His whole soul is filled with unutterable sorrow that he has slighted and grieved his compassionate Saviour. Such mourning is precious, for it will yield the peaceable fruits of righteousness. The worldling, from his stand-point, may pronounce this sorrow a weakness; but it is the strength which binds the penitent to the Infinite One with links that cannot be broken. It reveals that the angels of God are bringing back to his soul the graces which were lost through hardness of heart and transgression. To confess and deplore one’s errors evinces an excellence of character capable of discerning and correcting them. The tears of the penitent are only the clouds and the raindrops that precede the sunshine of holiness, the sorrow that heralds a joy that will be a living fountain in the soul. Men are sowing in God’s great field with toil and tears, yet with patient expectation; and they will be blessed, for the heavens will open and the rain will fall, insuring a bountiful harvest. Then when the Reaper comes, he will return with joy bringing home his sheaves.”
2 Corinthians 7:10 KJV, “For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death.”
1 John 1:9-10 KJV, “If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. If we say that we have not sinned, we make him a liar, and his word is not in us.”
It is a blessing to realize our sins are forgiven. The Law of God (10 Commandments) shows and convicts us of sin. Christ’s sacrifice is the only One acceptable offering to the Father to restore us to Him. Jesus, the Son of God, is our only remedy. Our part is to cooperate and mourn for our sins which caused the Son of God to die. Then joy comes to us knowing Jesus prevailed and we can overcome as He overcame.
Psalm 30:5 KJV, “For his anger endureth but a moment; in his favour is life: weeping may endure for a night, but joy cometh in the morning.”
Sincerely in the Blessed Hope.
