GOD IS SPIRIT:
John 4:24 KJV God is a Spirit: and they that worship him must worship him in spirit and in truth.
GOD IS LIFE AND GOD IS LIGHT:
John 1:4-8 KJV In him was life; and the life was the light of men. 5 And the light shineth in darkness; and the darkness comprehended it not. 6 There was a man sent from God, whose name was John. 7 The same came for a witness, to bear witness of the Light, that all men through him might believe. 8 He was not that Light, but was sent to bear witness of that Light.
GOD IS LOVE:
1 John 4:8 KJV He that loveth not knoweth not God; for God is love.
GOD IS A CONSUMING FIRE:
Hebrews 12:29 KJV For our God is a consuming fire.
The statement that GOD IS SPIRIT means that He cannot be confined to a physical body, nor to dimensions of space and time. He is the Invisible, Eternal God who was, who is, and who will be:
John 1:18 KJV No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him.
Because God is Spirit, He can say:
Matthew 28:20 KJV Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
Matthew 18:19-20 KJV Again I say unto you, That if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven. 20 For where two or three are gathered together in my name, there am I in the midst of them.
Hebrews 13:5 KJV Let your conversation be without covetousness; and be content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee.
