For those who have received God’s calling and conversion, “he who endures [perseveres] to the end shall be saved” (Matthew 24:13). When the New Testament church began, almost all the members were Jews or Jewish proselytes. Initially, they were filled with gratitude and zeal, but with increasing persecution and other trials, they were increasingly losing faith, zeal and commitment. Hebrews is largely a brilliant sermon with the theme of the necessity of spiritual perseverance, emphasizing how the New Covenant that focuses on Jesus Christ is far superior to the Old Covenant.
