Galatians 3:15-18 - The Promise To Abraham And His Descendant
15 To take an illustration from human life, my brothers. Once a man's will is ratified, no one else annuls it or adds a codicil to it. 16 Now the Promises were made to Abraham and to his offspring; it is not said, 'and to your offsprings' in the plural, but in the singular and to your offspring ??which is Christ. 17 My point is this: the Law which arose four hundred and thirty years later does not repeal a will previously ratified by God, so as to cancel the Promise. 18 If the Inheritance is due to law, it ceases to be due to promise. Now it was by a promise that God bestowed it on Abraham.
