Isaiah 43:2

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

The Lord does not promise us immunity from trial and trouble; we shall have to go through waters and rivers, and shall have to pass through fires and flames; it is through much tribulation that we must enter the kingdom of God; but he does promise that no harm shall come to us from it all. "We know that all things work together for good to them that love God;" - that waters, rivers, fires, and flames bring us benefits and blessings, and that they shall none of them bring a course upon us.
