19 Take refuge in God Who passes not away nor is changed. Restrain laughter by suffering, and mirthfulness by sorrow. Console suffering by hope, and sadness by expectation. Believe and trust, you that are wise, for God is He Who guides you; and if His care leaves you not, there is nothing that can harm you. If one man by another man, the lowly by the great, can be saved, how much more shall the refuge of God preserve the man that believes? Fear not because of adversaries who with violence come upon you. He will watchfully guard your soul, and hurtful things become profitable. No one shall lead you by compulsion, save only where there is freedom. No one falls into temptation, that passes the measure of his strength. There is no evil in chastisement, if so be that freedom is willing. The doings are not perverse of freedom, its will is perverted.
