"The Lord will strengthen him upon the bed of languishing." (Psalm 41:3)
Remember that this is a promise to the one who considers the poor. Are you one of these? Then take home the text.
See how in the hour of sickness the God of the poor will bless the one who cares for the poor! The everlasting arms shall stay up their soul as friendly hands and downy pillows stay up the body of the sick. How tender and sympathizing is this image; how near it brings our God to our infirmities and sicknesses! Whoever heard this of the old heathen Jove, or of the gods of India or China! This is language peculiar to the God of Israel; He it is who deigns to become nurse and attendant upon good men. If He smites with one hand, He sustains with the other. Oh, it is blessed fainting when one falls upon the Lord's own bosom and is born thereon. Grace is the best of restoratives; divine love is the safest stimulant for the languishing patient; it makes the soul strong as a giant, even when the bones are breaking through the skin. No physician like the Lord, no tonic like His promise, no wine like His love.
C.H. Spurgeon
