No matter how serious the trial, how deep the distress, how great the affliction, God will never desert us. He never has, and He never will. He cannot do it. It is not His character. He is an unchanging Being; the same yesterday, the same today, and He will be the same throughout the eternal ages to come. We have found that God. We have made Him our friend by obeying His Gospel; and He will stand by us. We may pass through the fiery furnace, we may pass through deep waters; but we shall not be consumed nor overwhelmed. We shall emerge from all these trials and difficulties the better and purer for them, if we only trust in our God and keep His commandments.
George Q. Cannon
Fear thou not; for I am with thee: be not dismayed; for I am thy God: I will strengthen thee; yea, I will help thee; yea I will uphold thee with the right hand of my righteousness.
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…Fear not: for I am with thee
Isaiah 43:2, 5
