If we had not sinned in the garden or passed the test and did not eat of the forbidden tree is also a mute question now...at some point we would have grown as a species and matured into something truly wonderful; reading about what happens in the resurrection gives us some clues as to what God had planned for us from the beginning.
In John 14 when Philip asked the Lord to just show them The Father and they would know Jesus was Messiah, Jesus gave Philip a Physics lesson regarding dimensions and dimensional capabilities. In Philips state then, all he could see of God was where God intersected his 4D reality as Jesus. BUT when we see Him this coming time we will see Him as He is ... i.e., we will be in a higher dimensional state and be able to see Him as He is in His higher dimensional state.
"Wherefore, comfort one another with these sayings."
