Some ask these questions, among other questions; where does God come from, who created Him, how long has this earth been in existence, etc., etc.? No man can truthfully answer these types of questions, because no man knows for sure. What would they do with that information even if they did have access to it? Probably nothing any different than what they are doing now. But, one can study the KJV Bible, seek the truth from His word (John 17:17), and do their best to learn as much as possible. The point is, no man knows what God knows; never has and never will.
Ecclesiastes 3:11 He hath made every thing beautiful in his time: also he hath set the world in their heart, so that no man can find out the work that God maketh from the beginning to the end.
[Does any man know what God has done in His time? Does any human know how long God or His creation have existed? Many humans think they know much, but do they really? Humans are so limited in every way. Can we see everything God has created and done? No way].
Ecclesiastes 8:17 Then I beheld all the work of God, that a man cannot find out the work that is done under the sun: because though a man labour to seek it out, yet he shall not find it; yea farther; though a wise man think to know it, yet shall he not be able to find it.
[Many think they have discovered what God knows. Have they or will they ever discover what God knows? The answer is no!!! Many think that what they believe is true and what others believe is false; they think they are wise. Are they? No way].
Romans 11:33 O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out!
[Wisdom, knowledge and judgments that come from God are rich and beyond what any human can comprehend].
He does tell us to seek the wisdom and knowledge that comes from Him; it helps us in this life and the afterlife. He will give us what we can handle, nothing more, nothing less. We must ask for it; see James 1:5. Godly wisdom is described in James 3:17. Worldly wisdom is described in James 3:15. Will worldly wisdom help you in either life? Might be something to meditate on. Other pertinent verses: Deuteronomy 29:29; Proverbs 1:7, 3:13, 4:5 and 4:7. Study your KJV Bibles completely, book by book, chapter by chapter and verse by verse.
