“Having been justified by his grace, we might become heirs, having the hope of eternal life” (Titus 3:7, NIV). When we believed God announced a judicial verdict: we are now adopted as children of God. We did not earn it; it was by his grace. This legal declaration means that we are also heirs of our Father, just as an adopted child on earth becomes a legal heir of their parents. One big difference is that our Father will never die and will never give up his “possessions”; rather, he gives his inheritance when we die and he has infinite possessions to bequeath. And what do we inherit? Eternal life. That is, we inherit from him a participation in his eternal life. We inherit his bliss, his love, his harmony, his freedom from corruption, his freedom to always choose good, his glory (1 Cor. 15:43), and his image (1Cor. 15:49). We will be what were originally meant to be, Adamic people who will fulfill the original missions given to Adam.
