Weeping may endure for a night, but joy comes in the morning (Psalm 30:5).
God rebukes, and God makes glad. Just one repentant thought eases the wrath of God; for God is not angry at men as an enemy is angry, but His anger toward men is as that of a father toward his children. His anger is momentary, and His mercy is infinite. If He rebukes you in the evening, He causes you to rejoice in the morning; men know Him best in His rebuking and in His mercy. O my brethren, if men constantly knew and recognized God as the Doer of good, they would never know Him as Rebuker and Judge. Behold, God rejoices more when we recognize Him by His mercy than by His anger.
However, there are very ungrateful and thoughtless people who never remember God when He grants mercy, but remember Him only when He chastises and rebukes them through sickness, death in the family, failure and shame before men, fire, the sword, earthquake or flood, or numerous other punitive rods and sticks with which He chastens the unawakened, reminds the ungrateful, brings the errant to their senses, and reminds everyone that He is the Creator and Lord, the Giver of Gifts and the Judge.
Weeping may endure for a night, but joy comes in the morning. These words also mean that the night is for weeping and prayer, for repentance and divine contemplation. The night especially is for repentance, and there is no true repentance without tears. At night a man thinks without hindrance about his deeds, his words, and his thoughts, and repents for all that he has done contrary to God's law.
If a man weeps in repentance at night, then he will rejoice during the day. He will rejoice as a newborn, as one bathed, as one alleviated from the burden of sin. But, if he spends the night in sin and senseless revelry, a sorrowful and tearful day will dawn for him.
O Lord Jesus Christ, our Savior and Teacher, rebuke us, but forgive us; chastise us, but save us.
To Thee be glory and praise forever. Amen.
