When thou passest through the waters, I will be with thee; and through the rivers, they shall not overflow thee: when thou walkest through the fire, thou shalt not be burned; neither shall the flame kindle upon thee. – Isaiah 43:2

Thou hast been in deep waters; hast thou been drowned? Thou hast walked through the fires; hast thou been burned? Thou hast had six troubles; hath He forsaken thee? Thou hast gone down to the roots of the mountains, and the weeds have been wrapped about thy head; hath He not brought thee up again? Thou hast borne great and sore troubles; but hath He not delivered thee? …The past is vocal with a thousand songs of gratitude, and every note therein proveth by an indisputable logic that He will not forsake His people.

Did ever any perish trusting in Christ? I have heard that some whom Jehovah loved have fallen from grace, and have been lost. I have heard lips of ministers thus prostitute themselves to falsehood, but I know that such never was the case. He keepeth all His saints; not one of them hath perished; they are in His hand, and have hitherto been preserved. David mourneth, “All thy waves and thy billows have gone over me;” yet, he crieth, “Hope thou in God, for I shall yet praise Him.” Jonah laments, “The earth with her bars was about me for ever;” and yet, erelong he says, “Salvation is of the Lord.” Ye glorified ones above, through much tribulation ye have inherited the kingdom, and wearing your white robes, ye smile from your thrones of glory and say to us, “Doubt not the Lord, neither distrust Him, He hath not forsaken His people nor cast off His chosen.”~ C.H.
