A difference many Christians fail to recognize is the difference between the Holy Spirit in us and the Holy Spirit upon us. The Holy Spirit “within” saves us. The Holy Spirit “upon” empowers us. That may seem like a small difference, but the implications are quite large. God never intended for us to simply be saved, but to be witnesses. But in order to be effective witnesses, we need the power of the Holy Spirit upon us. Otherwise we are limited to our own natural abilities.
