What is the significance of being children of promise?

In Galatians 4, Paul identifies those who believe in Christ as children of promise, contrasting them with those who are born of works under the law. This distinction emphasizes that salvation is based on God's promise and grace rather than human effort or adherence to the law (Galatians 4:28). The implication of being a child of promise means that believers receive the full inheritance of eternal life and salvation through faith in Jesus Christ. This relationship allows believers to enjoy the liberties and blessings associated with being part of God's family, free from the bondage of legalism and able to walk in the Spirit. Such understanding fosters assurance and encourages believers to live in the light of their identity as God's children, marked by His grace.
