the need to persevere

I'm being refreshed in reading a number of books, and one of them, Kept by the Power of God, by I.Howard Marshall, I'm finding helpful right now. A Scottish scholar, Marshall shows us exegetically from Scripture the real danger that exists if believers in Jesus don't keep going forward in growth in grace. He proposes from Scripture that if we don't go forward, we will go backward, and we're in danger of losing what we once had- our salvation. Particularly in his work on the book of Hebrews, I think Marshall presents a compelling case for his thesis. I'm not done with the book yet, but I'm enjoying it because I think it brings out what so many, in one way or another, negate. And reading other books at the same time helps me avoid being suffocated by the difficult subject matter.

Any thoughts on this?
