The Vedas confirms God is Atman (spirit), the innermost Self.
Rig Veda: ~ The Atman is the cause; Atman is the support of all that exists in this universe. May ye never turn away from the Atman the innermost self. May ye never accept another God in place of the Atman nor worship other than the Atman?" (10:48, 5)
Bible says: ~ “God is a Spirit, and they that worship him must worship him in spirit and in truth (John 4:24)”,
Christ means the ultimate truth. Ultimate truth is the Spirit. Christ is not physical. Christ is the Spirit. Christ is the innermost Self. The Christ is birthless and deathless because Christ is formless, timeless and spaceless existence.
The birth, life, and death happen within the illusory world, which is created out of Christ, which is present in the form of the Spirit.
The Spirit is the root element of the universe. The Spirit is present in the form of the Soul, the innermost Self. The Soul is present in the form of the consciousness. From the Spirit, the universe comes into existence. In the Spirit the universe resides. And into the Spirit the universe is dissolved. The Spirit is the parent of all that is there is.
In Yajurveda – chapter- 32:~ It has been said that God Supreme or Supreme Spirit.
