"Retroactive Faith" is a dangerous way to believe. It is a belief based on God having brought you through a situation… an after-the-fact basis for trust. The opposite of this might be "Proactive Faith" which is a belief based on God being active through an uncertain situation… a before-the-fact and also a during-the-fact basis for trust. It is true that faith is strengthened by history (seeing God's hand at work) and therefore the concept of remembrance is a vital and healthy component to faith. But faith must always be a forward looking unconditional trust given to God for what God will do — even if we are fearful or uncertain of the immediate outcome.
