The finding of a lost thing brings much gladness, yet the searching teaches us a greater truth. You thank God that you still have the string which must be loaded by hand, and this is right, for you have seen that what remains is sufficient for the work. So often we set our hearts on ease and plenty, and when that is taken from us we despair, not perceiving that the humbler portion still serves. As the body has parts which seem less honorable, yet upon these we bestow more abundant care, that the whole body may be preserved and thrive.
The spool cap too is missing, and you know where the spare caps lie, if only the bag would be found. Do not let this loss make your heart hard, for from hardness grows unbelief, and from unbelief a turning away from the living God. Rather, seek that bag as you would seek a lost child, leaving no corner unsearched, yet with a mind stayed on Him who orders all things. If you find it, give thanks and hold it fast; if not, yet give thanks still, for the weed eater may yet be mended, and its work accomplished.
Faith like the mustard seed is small and unassuming, yet it moves mountains when need calls, and far greater things than finding pre-filled string. The saints did not always remove mountains, for there was no need, yet the power was within them. So too with you: what is needful shall be supplied, whether by finding or by patience. Turn often to the Psalms, which are a storehouse of remedies for every state.
There you will hear that a man’s days are as grass, and his glory does not follow him down; what then is a bag of string, or a missing cap, that they should disturb the soul? Trust in God, and let not the fret of small things overshadow the blessing of what is still in hand. Search diligently, pray earnestly, and then leave the matter in His keeping, for He cares for the lesser members even as the greater, and nothing which belongs to His own is truly lost.
