If it was your son then it wasn't you, even if it was your twin it still wouldn't be you. Both of you have your own spirit therefore 2 different entities. Same with God
and his Son Jesus Christ. Although God, his Father, dwelled in his mortal body during his ministry as it was his Father that told him what to say and do.
John 8:28,
John 8:54 "Jesus answered, if I honor myself, my honor is nothing: it is
MY FATHER that honoreth me; of whom ye say, that
HE IS YOUR GOD."
The pure in heart was not Phillip at that time most definitely as he was an unregenerate human as the Holy Ghost had not been given yet. So in looking upon
Jesus he was definitely not looking at God. The only way a person sees the Spirit is by the physical actions it manifests but the human eye cannot see it as the
human eye can only pick up 3% of the visible wavelength of light that is in the creation. We miss 97% of what is there. Makes it easy to understand why no
man hath seen God, but they did see the physical manifestations that God did that were referred to as works. Blind getting sight, dead raised, lepers cleansed,
etc.... Even we who have the Spirit indwelling us do these things but we know its not us doing them it is the Lord that does them but he allows us to tell people
what is going to happen, or what just did happen. They still don't see him but they see the manifestation of the Spirit in say the healing they witnessed.
The pure in heart will see God once the change has come and we will also see Jesus as we will be like him.
