Not Two Lines

We hear much about the “spiritual seed” and the “literal seed” of Abraham. If that contrast meant anything at all, it would mean a fanciful seed as opposed to a real seed. The opposite of spiritual is fleshly, and the fleshly seed, as we shall see later on, is not the real seed, but only a bond-servant, to be cast out, having no share whatever in the inheritance. So there is no fleshly seed of Abraham. The spiritual seed, however, is a literal, or real, seed, even as Christ is “a quickening Spirit,” and yet most real. It is possible for men walking about in the body, in this world, to be wholly spiritual, and such they must be, or else they are not children of Abraham. “They that are in the flesh can not please God.” “Flesh and blood doth not inherit the kingdom of God.” There is only one line of descendants from Abraham, only one set of real children, and they are those who are of faith,—those who, by receiving Christ by faith, receive power to become sons of God.GTI 129.1
