The common practice of most believers is to pursue an intellectual (academic) search for answers to validate their beliefs. For example, you refer to Jesus as God’s Son. That’s textbook perfect. What you have missed, what the natural mind cannot grasp on its own, is that you are that same Son–One Life in the Father. The Life within you (your Essence or Spirit), is the same Christ-Nature that is seen in Jesus.
We’ve never been shown in church how to let go of our identity as individual person, so we continue to believe ourselves to be separate from God. You cannot be separate from God because God is LIFE Itself. Believing alone, unfortunately, will not get you there, because believing is all done with the mind. While you are figuring all this stuff out, you might notice that within you, there is yet no awareness of your ONENESS in God, which is what Jesus came to reveal. “Father, I pray that they may be one as we are one”.
