"And the glory of the Lord abode upon mount Sinai, and the cloud covered it six days: and the seventh day he called unto Moses out of the midst of the cloud." (Exodus 24:16)
We know very well that the human mind cannot comprehend or encompass the person of God. We can know what God is not, but in this earthly life it is impossible for us to say, "I know what God is." We never can know because God belongs to a realm entirely different from ours. The great God exists in awesome wonder. He is uncreated holiness, high above all the things that the hands of mankind have made.
There is neither preacher nor teacher anywhere in the world who can say, "Let me tell you all about God!" God told Moses and Israel, and He tells us: "Always there will be the cloud about Me. Always there will be a veil covering My person. While you are on My earth, you will sense this obscurity, for I Am who I Am!"
And I can say this from personal experience: After you have known God and walked with Him by faith for fifty years, growing daily in His grace and the knowledge of Him, you will still see a cloud on Mount Sinai. You will still sense the obscurity. Your mind and your spirit will still bow before Him. Your day of full comprehension is yet to come.
I long for that day, Lord, when the cloud is completely removed and I shall know You completely. Amen
God is Ineffable
"For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God." (1 Corinthians 2:11)
We can best conceive of God by conceiving of what He is not. We can always knows what God is not, but we can never know quite what God is. The greatness of God's mind leaves all our soaring thoughts behind. God is ineffable (incapable of being expressed in words), inconceivable and unimaginable.
As I said, we are driving to the use of negative statements when speaking about God. When we speak of the self-existence of God, we say God has no origin. When we speak of God's eternity, we say God has no beginning. When we speak of the immutability of God, we say God has no change. When we speak of the infinity of God, we say that God has no limits. When we speak of the omniscience of God, we say that God has no teachers and cannot learn.
Well now, the Scripture takes this negative method too. Scripture says the Lord "fainteth not, neither is weary" (Isaiah 40:28) and that He "cannot lie" (Titus 1:2). It says "I am the Lord, I change not" (Malachi 3:6). It says "with God nothing shall be impossible" (Luke 1:37)....
Teach me, Lord, that I might know all of You that I can within the limits of my humanity. I await the day when I will more completely know who You are. Amen
