Before the “Big Bang” is “I am”.
Creation by God, not a scam.
He said: “Let there be light”.
And there was: With God’s might.
The Triune, eternal “I am”.
As it so happens, the triune God is introduced early in the Bible, in Genesis 1:1-3
1 In the beginning God created the heavens and the earth. 2 Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters. 3 And God said, “Let there be light,” and there was light.
This establishes a few things. There was a beginning. Before the beginning was God. He is named Elohim (the strongest strong one). The covenant name Jehovah is introduced in Genesis 2:4b: in the day that the LORD God made the earth and the heavens, and this points to the fact that it is Jehovah, the Father that is the creator. Verse 2 points to the Spirit of God hovering over the waters, that is the Holy spirit. Verse 3 mentions God said, Let there be light. That is the word. As the Apostle John wrote in John 1:14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth. This refers to the Son, the Lord Jesus Christ.
There we have it: The triune God, Father, Son and the Holy spirit defined already in Genesis 1:1-3.
We are bound in time and Space. God is not. Before the Big Bang, time and space has no meaning for us. Therefore it is not possible for us to even begin to comprehend the greatness of God. As the Prophet Isaiah wrote a long time ago (In chapter 55)
6 Seek ye the Lord while he may be found, call ye upon him while he is near:
7 Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the Lord, and he will have mercy upon him; and to our God, for he will abundantly pardon.
8 For my thoughts are not your thoughts, neither are your ways my ways, saith the Lord.
9 For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.
10 For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater:
11 So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.
