God is Spirit
John 4:24 God is a Spirit: and they that worship him must worship him in spirit and in truth.
The correct translation of Jesus’ words are “God is Spirit” for there is no article in the Greek language. He is not just another spirit for there is none other like Him nor is His composition of a common spirit. He is the sum of the Eternal Spiritual realm. The Eternal Spiritual realm does not have it’s equal in the physical realm of the creation for He is before creation and therefore is not subject to it. Neither do we have a clear picture of the essence of God for all we know is based on our understanding of the created and from within the creation.
However there are some things that God has revealed about Himself that helps us to comprehend who and what He is. For example, Jesus said in Luke 24:39 A spirit hath not flesh and bones, as ye behold me having. He is not composed of matter such as is all of creation for He is before creation and by Him all of creation exists. He is Spirit which is existence before and beyond time and space. This raises a question about places in the Scripture that reference God as having body parts, such as hands, feet, eyes and ears. These Scriptures are what is called anthropomorphic and symbolic representations to help us within the finite to comprehend something of the infinite and to give us a concept of a real and personally involved God.
The second revelation of God is that He is invisible. The Bible states that He is the invisible God (Romans 1:20, Colossians 1:15, I Timothy 1:17). The Israelites recorded that they saw “no manner of form” when the Lord appeared before them at Mt Horeb (Mt. Saini). Further, God told Moses that no man can see God and live (Exodus 33:20). John stated “No man hath seen God at any time” (John 1:18). There is the promise that the redeemed will eventually see Him (Psalms 17:15, Matthew 5:8, Hebrews 12:14, Revelation 22:4).
The third revelation that God has given is that He is alive. The Bible declares Him to be the living God 30 times in Scripture (Some examples: Joshua 3:10, I Samuel 17:26, Psalms 84:2, Matthew 16:16, I Thessalonians 1:9). In John 14:6 Jesus declared that He is “the Life”. When Adam’s body was formed from the dust of the ground, God breathed into his nostrils, the breath of life and man became a living soul. We have our existence out of the very breath of life itself. He is not only alive but he is the source of all life (John 5:26, Psalms 36:9). This includes all plants, animals, human, spiritual and eternal life. Since all life forms originate from God, they do not equate to God, but only aid in our understanding of Him. Because nothing physical can properly portray the glory and majesty of God, man was forbidden to make an idol of God. It is noteworthy that all of the idols of man are dead, whereas God is alive.
Finally, we come to the fourth revelation that God has given of himself and that is of individuality. We speak of God in the singular and quote: Eph 4:6 One God and Father of all, who is above all, and through all, and in you all. God is one and beside Him there is no other. Some accuse Christians of having three Gods; God the Father, God the Son and God the Holy Spirit. Though it may sound like they are three separate Gods, they are all one in the same way that we are individuals. I have a body but that is not all there is to me; I have a soul and mind, yet that is not all there is to me; and I have a spirit nor is that all there is to me. The body, soul and spirit are all one person and only describe different dynamics of this complex person that I am. God is a trinity and he made man a trinity so that he might comprehend something of the dynamic and complexity of God. God is described as having intellect, sensibility and volition. He is represented as speaking, seeing, hearing, anger, compassionate, etc. We speak of God as one being, in three persons. In answer to the question, How can that be; it is answered in the same way that I am one person, with three dynamics of physical, volitional and spiritual. I can be at the same time; a father, a husband and a son, depending on the position of consideration, and be without conflict.
In our efforts to know God, our difficulty is not in the teaching of the Scripture, but in our own limitations that we place on God. He is greater than all that we can comprehend or know. It is like viewing the mountains for the first time. At first they seem to be quite small and insignificant but as you draw closer to them they seem to grow bigger and bigger until they seem to each to the sky. The truth is that they were always that big but your understanding is what has grown. Getting to know God will change your perception of Him.
