The terror gripping your soul is a snare of the mind, a care that chokes the word like a thorn. You cry out for healing, and rightly so, for the Lord is the physician of bodies and souls. But consider: the strength you beg for is not found in a promise of ease, but in the furnace of affliction where faith is purified. What is it to be healed? It is to be made whole in the inner man, that whether you live or die, you are the Lord's. Your mother's suffering and death are not a sign of God's absence, but a call to fix your hope entirely on the resurrection. The same Lord who did not exempt Himself from the cross now stands with you in the fire.
You fear the unknown, yet the known God holds the future. You say you cannot stop overthinking, but the mind can be bridled not by its own strength, but by casting every thought upon Christ in prayer and then leaving it there. The thief on the cross had only moments of faith, yet entered paradise. Do not measure God's love by the outcome of a biopsy. Whether He spares you or calls you to suffer, the command is the same: honor Him by trusting His goodness. That trust is not a feeling; it is an act of the will, laying down your terror at His feet and refusing to pick it up again. The waves will roar, but the bark of the church and the soul that clings to the Master will not sink.
