For his anger endureth but a moment; in his favor is life: weeping may endure for a night, but joy cometh in the morning. (Psalm 30:5)
A moment under our Father’s anger seems very long, and yet it is but a moment after all. If we grieve His Spirit, we cannot look for His smile; but He is a God ready to pardon, and He soon puts aside all remembrance of our faults. When we faint and are ready to die because of His frown, His favor puts new life into us.
This verse has another note of the semi-quaver kind. Our weeping night soon turns into joyous day. Brevity is the mark of mercy in the hour of the chastisement of believers. The Lord loves not to use the rod on His chosen; He gives a blow or two, and all is over; yea, and the life and the joy, which follow the anger and the weeping, more than make amends for the salutary sorrow.
Come, my heart, begin thy hallelujahs! Weep not all through the night, but wipe thine eyes in anticipation of the morning. These tears are dews which mean us as much good as the sunbeams of the morrow. Tears clear the eyes for the sight of God in His grace and make the vision of His favor more precious. A night of sorrow supplies those shades of the pictures by which the highlights are brought out with distinctness. All is well.
– C.H. Spurgeon
