RC 358.3
(Reflecting Christ 358.3)
The Lord is compelled to fortify the soul against self-sufficiency and self-dependence, in order that the worker shall not regard his failings as virtues, and thus be ruined by self-exaltation. Sometimes the Lord makes His path to the soul by a process that is painful to humanity; the work of purifying is a great work, and will always cost man suffering and trial. But he must pass through the furnace until the fires have consumed the dross, and he can reflect the divine image. (RC 358.3) MC VC
