It is a heavy trial indeed when the covenant of marriage, which should be a picture of Christ and His Church, is rent asunder. The Lord has declared, "I hate divorce," and we dare not bless what He has cursed, nor call that union which He has severed. Yet we may, with all tenderness, pray for strength and help for your son in this dark hour.
The strength he needs for his daily labour will not come from himself; all strength apart from God is derived and measurable, and must come to an end. They that wait upon the Lord shall renew their strength. Let him therefore cry to God for might, not a fussy, frantic energy that exhausts itself, but that quiet, calm strength which is the gift of the Most High. It is not to his credit that he should be weak; the glory of a man is his strength, and especially his spiritual strength. When a man learns to work with God's strength alone, he can do all things. Let look away from his own powers and abandon self-reliance entirely, laying hold on the Divine might. So shall his work be done to a nobler tune, with more expectancy and faith.
As for sleep, it is a gift which the Lord giveth to His beloved. There is a sleep of security, a sleep of contentment, which the Christian may know even in the furnace of affliction. If the soul is stayed upon Jesus Christ, then though the night be long, peace may come. But remember, there is also a sleep that is forbidden, a slumber like that of the sluggard in the Proverbs, who cried, "A little more sleep, a little more slumber." In times of sorrow and temptation, we are warned, "Let us not sleep, as do others." Many a child of God has found his strength ebbing away, as Samson's did, while he slept in Delilah's lap. Let your son watch and pray, lest the weariness of his trial be mistaken for the sleep of security, and so his soul suffer loss. Ask the Lord not merely for natural rest, but for that holy composure which comes from rolling every burden upon the great Burden-bearer.
It is a thing greatly to be desired that he should be strengthened, for then he is prepared to do the Lord's work effectually, even in the midst of this storm. The Divine grace that works in him does not lull him into sloth; where the Holy Spirit works, He makes men work. So let be up and doing, yet knowing that his labour is not his own. The weary limbs of the body may find rest, but the soul must never sleep its way to glory. There is a sleep of death, too, a blessed rest that remains for the people of God, but while we are in the field, the wolves are howling, and the powers of evil never suspend their activities. Watch therefore with holy vigilance.
Bear this in mind: the Lord is the glory of our strength. Every particle of power, mental or physical, comes from Him. Have we not learned to say, "Thou art the glory of their strength"? Let us not foolishly imagine that we can of ourselves withstand this torrent. While he is yet without strength, let him believe that Christ died for the ungodly. That is the one foundation. Cast the soul wholly upon the finished work of Jesus, and then out of that living union will flow strength for each day's duty and rest for each night's weariness.
We will join with you in praying that God would uphold , that he may do his work faithfully and find nightly repose, not as the world gives, but as Jesus gives. We will pray that all the family would bow beneath the mighty hand of God, seeking His face and His salvation. And may none of us presume to bless what His Word condemns, but rather seek that mercy which heals every breach and restores the soul.
