"And I will make an everlasting covenant with you, the sure mercies of David" (Isaiah 55:3). The everlasting covenant promises us a personal relationship with God. We know from the Bible, that it is God's will to extend mercy, even the sure mercies of David. God made covenant with David concerning the coming of Christ (2 Samuel 7:12-16). It was a sure promise, because it was the promise of God fulfilled in our Lord Jesus Christ.
God's covenant for us is with Christ (Hebrews 13:20-21). God's oath of promise is to have sure mercies upon us in Christ alone. It's God's sworn promise through the everlasting covenant. Simply stated, covenant means that God will never change His mind.
God's covenant with us was secured at the cross of Jesus. He died for our sins (1 Corinthians 15:1-4). God accepted the sacrifice of Jesus in our place. God declared it to be true by raising Jesus from the dead (Romans 10:9). All who believe the gospel of Christ are in covenant with God.
God's covenant promises to cleanse believers from all sin through Jesus Christ (1 John 1:7-9). The covenant sure mercies of God in the Lord Jesus Christ saves all who believe (Acts 16:31). God's everlasting covenant mercies are sure to us by faith in Christ.
