Trust is an essential ingredient for true living. There is the initial decision to trust God through Christ's redemptive work, allowing Him to assume control of my life as well as my eternity. There is the discipline to trust moment by moment as I grow in grace and knowledge of the truth.
However, something must precede my decision to trust God at some particular point in time; something must be motivating me to continually seek Him. Why would I want to trust Him? Why would I want to trust Him more... or again?
