Questions to ask Oneness Pentecostal believers

The following questions are not "stoppers." That is, they are not questions to ask Oneness people so you can "stump them for sure." Instead, they are questions to ask to generate conversation. It is during the conversation that real witnessing occurs.

Of course, I have found some of these questions to be more difficult than others for the Oneness person to adequately answer. In fact, two of them no Oneness Person has adequately answered at all. Which are they? Try them out.

Is Jesus His own Father?
If Jesus' will and the Father's will were identical, then why did Jesus express the desire to escape the cup but resigns Himself not to His own will, but the will of the Father? See my article on this.
Was Jesus praying to Himself in the Garden of Gethsemane?
If Jesus was praying to the divine side of Himself, then isn't He still praying to Himself?
Why was Jesus not saying, "Not My will, but MY will be done?" if there is only one person and one will involved when He was praying in Luke 22:42 & Matt. 26:39.
If baptism is essential for salvation, then what happens to someone who repents of sin, accepts Jesus as Savior, walks across the street to get baptized but is killed by a car. Does he go to heaven or hell?
1. If he goes to heaven, then baptism isn't a requirement is it?
2. If he goes to hell, then faith in Christ isn't sufficient to save him is it?
Since the Bible teaches us that Jesus is in bodily form now (Col. 2:9), then how does the Oneness Pentecostal person maintain that God is in the form of the Holy Spirit? Also, when Jesus returns, will He return in His body? Will God's form then revert to the form of the Son at a later date?
If God is only one person, why did Jesus say in John 14:23, "If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him." If God is only one person, why does Jesus say, "we"?
Oneness theology teaches that God was in the mode of the Father in the Old Testament. God was seen in the OT (not as a vision or a dream or an angel in the following verses: Exo. 6:2-3; Gen. 19:24; Num. 12:6-8). But, Jesus said no one has seen the Father (John 6:46). If they were seeing God Almighty (Exo. 6:2-3) but it wasn't the Father, then who was it?
