Faith is not a One Time Inoculation

The faith lesson I take from 2 Chron 16.7-9. Asa had won a great victory over a huge army of Ethiopians early on in his reign because he trusted in the Lord and the Lord provided a great victory. The next time a big test came up, he trusted the king of Syria, rather than the Lord. His punishment was that he would have constant war for the remainder of his reign.

You cannot assume that, because you had faith once, you are good to go for the rest of your life. A huge spiritual victory is no guarantee that the next time you have a battle you will also win a huge spiritual victory based on the last one. Faith is a living, breathing, never-sitting-still, never satisfied thing. You either grow in the faith or you go backwards; there is no such thing as "making it;" there are no plateaus upon which we may rest on our laurels. It is always and ever upward in the life of faith; trusting on God to grow us.
