Charles H. Spurgeon wrote, "The whole burden of our salvation rests upon the faithfulness of our covenant God. The whole matter of salvation is centered on the attribute of God's great faithfulness."
God is faithful to the promises of the everlasting covenant (Hebrews 13:20-21). God is faithful to these four covenant promises for every believer in Hebrews 8:10-13. He is faithful to keep his word of oath to covenant promises. God has bound himself forever with his oath of covenant promises.
God is faithful to our salvation through the gospel. Jesus died on the cross as the everlasting covenant sacrifice. God is faithful to forgive and cleanse us from all sin, through the blood of Jesus (1 John 1:7-9). The power of God's covenant promises for you are proven forever through the resurrection of our Lord Jesus Christ.
God is faithful to save every believer in Jesus Christ our Lord. Jesus is the Yes and Amen of all the promises of God (2 Corinthians 1:20). God will not break his covenant word with believers. He has sworn with an oath. Our faith stands upon the covenant of God's great faithfulness in Christ. That's God's oath of promise to all who believe. To doubt God's word in the Bible is to doubt his great faithfulness.
God is faithful to guarantee our salvation. Our assurance of salvation is trusting God's faithful promises. The sure evidence is the resurrection of our Lord Jesus Christ (Romans 10:9). Jesus is every believer's covenant surety (Hebrews 7:20-22). A surety is a guarantee. God's promise of salvation is our assurance in Christ.
