Our emotions might suggest that God has deserted us but God has told us that He will never leave us or forsake us. Our feelings are blown and tossed by the seas of circumstance. God's Word is an anchor that holds solid. This principle is true for all kinds of situations. You may be overwhelmed by your needs and feel you need to take matters into your own hands to get what you want, but the Bible tells you to trust Him and He will supply your needs.
Love is a decision more than an emotion.
You may feel that you have really messed things up and that you have lost your salvation. But God tells you that you don't understand that true happiness cannot be found apart from Him. Having said all this, there is an obvious implication. We can't trust God's Word unless we KNOW God's Word. God's Word is our anchor, our map, our light for the darkness.
