Now we, brethren, as Isaac was, are the children of promise. But as then he that was born after the flesh persecuted him that was born after the Spirit, even so it is now. Galatians 4:28-29
As Isaac was a son of promise to Abraham, so all who trust in Christ Jesus, the Seed of Abraham, for pardon and forgiveness are the promised children of Abraham and inherit eternal life through faith in Jesus. But as Ishmael mocked Isaac, so those depending upon their own religious works or earthly church affiliation mock and persecute those trusting in Christ alone for salvation.
Grant that I trust in Thee alone, O Christ, that I might be a child of promise and inherit eternal life. Amen.
