The central theme of the Book of Hebrews is the supremacy of Jesus Christ over all Old Testament figures and systems. In chapter six, the author warns against spiritual stagnation and raises a pressing question: Can salvation be lost? By allowing Scripture to interpret Scripture, we come to see that salvation does not rest on the strength of one’s faith, but on the steadfast assurance found in Christ Himself, the ultimate fulfillment of everything to which the Old Testament pointed.
