God and His Word are not the objects of faith how we feel about things is. Consequently, our faith is at the mercy of our feelings. When we feel low discouraged depressed we go into a tailspin. We find ourselves in a vicious spiral where, depending on feelings to bolster feelings, we sink into the pit of despair. They are erratic, transient subject to what we eat, the weather, how much sleep we get, traffic, how things are going at work .
Feelings are deceptive capricious vulnerable.
Your feelings about God may change but God, Himself, does not. A person may feel God-forsaken, but they're not. That's God's promise. He stands behind it. Some put faith first before fact.
