Christianity was not established by man “wishing it into existence.” It began outside of man. And for that matter, it took more than God merely “wanting it to happen.” God actually did some specific things in order to create Christianity as the one true faith.
So what was required in order for Christianity to be established? It involved: (1) a sinless Savior; (2) the sacrificial death of the perfect Savior; and (3) the resurrection of the Savior from the dead.
Without those things happening, we would not have a path to the Father. We could have searched within ourselves all day long for godly spirituality, but that introspection would never have produced true religion or true faith. The work of establishing Christianity had to be done outside of us. In God’s design, this “outward” aspect of Christianity is central to knowing God. A person must look outside himself if he wants to have the kind of faith God accepts.
Man has always been tempted to look inside himself in hopes of being accepted by God. And just what does man find when he looks inside his own heart? He may see some honest efforts, and perhaps even a lengthy list of noble achievements. In addition, man can find some measure of sincere spirituality and faith within himself. But all of that is nothing compared to what man can find when he looks outside himself.
