The essence of God according to John 4:24 is that God is a Spirit. Being a Spirit, He can be everywhere so as to be called the Omnipresent One. The Spirit cannot be seen but its presence is felt. However, this Spirit according to John 1:1 has a Word with Him; and this Word is God. Now we have seen the Spirit and the Word. When we talk of the Spirit, we are also talking about the Word. Therefore, the Spirit and the Word are not two separate entities but are one and the same. This is the essence of God in the Old Testament - Spirit and Word. The Word can only be heard but not seen just like the Spirit.From Genesis, Exodus, Numbers, and Deuteronomy and throughout the Old Testament account, we can see how God dealt and manifested with them through His Spirit and Word. In Mt. Sinai, He spoke to His people but He was not seen at all. Therefore, we can conclude that the Spirit and the Word are one; and they are not in anyway separate from each other. As we continue with this study, let us proceed to the next step which is the manifestation of the Word of God.
