How do we know God made a covenant with Jesus Christ?

The concept of covenant is central to understanding the relationship between God and His people. In 2 Samuel 9, the mercy shown by David to Mephibosheth serves as a picture of the covenant that God made with Christ to redeem a chosen people. According to Scripture, God the Father entered into an everlasting covenant with the Son, establishing Christ as the surety and redeemer for those destined for salvation. Verses such as Romans 8:35-39 declare that nothing can separate the elect from the love of God in Christ Jesus, affirming that this covenant is secure and rooted in God's sovereign will. This covenant underscores the foundational truth of salvation by grace through faith, as all is accomplished through the work of Christ.
