How do we know that God's covenant is still relevant today?

The covenant that God made with Abram is not merely an ancient agreement but a part of God's redemptive plan that culminates in Jesus Christ. The everlasting covenant of grace, which includes promises made to Abram, is fulfilled in Christ, who is the promised seed (Galatians 3:16). Today, all who believe are included in this covenant because it rests on God's faithfulness and the work of Christ, the mediator of a new and better covenant (Hebrews 8:6). Thus, the covenant remains ever relevant as it speaks to God's unchanging nature and His commitment to His people.
