Jesus, the Incarnate Son of God, obeyed the Heavenly Father to the point of dying on a cross as a restitution for our disobedience.

Because of that, we all can become children of God once again and inherit eternal life. And even if you were the only person around, Jesus would become a man to carry & die on that cross. He is your personal Savior.
