How do we know the promises of the Covenant of Grace are true?
Answered in 1 source
The promises of the Covenant of Grace are assured because they are grounded in God's everlasting faithfulness and the completed work of Christ.
The certainty of the promises found in the Covenant of Grace comes from God's unchanging nature and Christ's perfect fulfillment of the covenant. Hebrews 13:20 speaks of the God of peace who brought back from the dead our Lord Jesus, connecting the promises of the covenant with the establishment of Christ's perfect sacrifice. The assurance lies in the fact that God Himself guarantees these promises, emphasizing His sovereignty and faithfulness throughout eternity. The Covenant provides a profound security to believers that their salvation is accomplished by Christ, who is the surety of a better covenant (Hebrews 7:22).
