Ok, but what actually were the simple answers that you gave to those questions, or what answers would you give to those questions if an adult asked them with genuine curiosity?
1. Where is god?
2. How do we see god?
3.Can we talk to god (and does he talk back)?
4. Why did people not like Jesus?
Adult answers:
1) His heaven is the third heaven that exists outside the bounds of our universe...a transcendent, spiritual place where God's holy kingdom resides. The first heaven is our earthly atmosphere, the second heaven is the expanse of the universe and the 3rd heaven is God's kingdom beyond that. God is not "the man living in the clouds" with fat, baby angels playing harps.
2) God's nature is divine and he expresses that nature in a trinity of persons in Father, Son and Spirit. The Father is Spirit and the Holy Spirit is spirit, but the Son exists in the form of humanity in the person of Jesus Christ. People have seen God through the incarnate son in Jesus Christ and one day believers will again see him face to face. We see God in the goodness and seemingly infinite expanse of his creation. We see God in his holy word. We see God in his body of believers. We see God in his redemptive work on Calvary's cross.
3) We speak to God in moments of prayer. For most God does not speak in an audible voice, but he has to some both past and present. He communicates to some in dreams and visions and for believers today it's the tangible presence of his Holy Spirit made manifest in our lives that's an amazing personal communicative experience (hard to even describe). His spirit literally exists within his believers...attached to us at the soul (if you will). More so than sight and sound, but the feeling of God indwelling his apostles is what emboldened them to move forward with his great commission proclaiming his death and resurrection, his righteouness, grace, mercy, justice and love. And doing so bodly without shame until their lives were extinquished.
4) It was the Pharisetical leadership in the Sanhedrin that despised Jesus and his teachings and charged him with blasphemy for proclaiming himself the messiah and claiming equality with God. The pharisees were repeatedly exposed and outwitted by Christ for their self-serving, disingenuous behaviors and they hated him for it and recruited the assistance of the Roman government to capture, brutally punish and ultimately put him to death via crucifixion at Golgatha (or Calvary). The pharisees held great influence and power over the Jewish people and easily managed to turn the throngs of Jewish people against Christ.
