What does it mean to be a child of promise?

A child of promise refers to those who are granted new life through faith in Jesus Christ, born not of the flesh but of the Spirit. This concept is rooted in the theological distinctions made in Scripture, particularly illustrated in the children of Abraham—Isaac, as the child of promise, versus Ishmael, born of the flesh. Similarly, believers are chosen by God, according to His purpose and grace, to inherit the blessings and freedom of the covenant of grace. As seen in Galatians 4:28-31, believers are seen as children of promise, signifying that we are heirs to God's kingdom and recipients of His mercy. This identity reassures us that God’s grace will sustain and preserve His children until the end.
