The major purpose of this magnificent passage of Scripture is to encourage the Jewish believers being addressed to hold steadfastly to their Messiah in unwavering faith. In so doing, it has blessed all of God's people throughout the generations.
Faith is the assurance of unseen spiritual realities.
Faith believes God's disclosure regarding atonement through the blood of the sacrificial lamb. These heroes for God carried out God's will for their lives. Their commitment to God and His promises was total, often in the face of death. True faith not only responds to what God asks, but also risks everything to obey Him. Each case illustrates the principle of faith in God, despite danger and sacrifice.
