perseverance obedience and preservation of the saints in Hebrews.

I agree with my brother FF Bruce (Epistle to the Hebrews, NICNT, 94):

“The conditional sentences of this epistle are worthy of special attention. Nowhere in the NT more than here do we find such repeated insistence on the fact that continuance in the Christian life is the test of reality. The doctrine of the final perseverance of the saints has as its corollary the salutary teaching that the saints are the people who persevere to the end.”
