I don't see how our views differ? God can be multiple places at once, since He IS omnipotent, right? So God was in Heaven controlling things while God went to Earth and was named Yeshua an died for our sins. SO God was also in Heaven when He sent the Holy Spirit, who is also God, into the hearts of all believers. Does the fact that God can be in 3 places at once freak you out? What's goin' on?
I think you are a Trinitarian and just don't know it!
