I think that mathematical patterns and the fine tuning of the Universe are interesting evidence for an intelligent creator, but I do not think they are "absolute proof". Because they need to be interpreted to mean this or that.
And God has given you, and all of us, that ability to interpret. We are endowed by His own gift to observe, evaluate, and perceive not just an Intelligent Creator, but the basics of His nature...
Romans 1:20 KJV
"For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse"
And I do not see how they lead specifically to "the God of the Bible".
The ability to see only comes through *seeking* to know God more fully - with ALL of our faculties - in prayer to His Spirit, in His creation, and in His Word. This is the Father drawing us to faith in His Son - through Whose Spirit alone He reveals the Father to us. That is the meaning of Christ's revelation.
It is then when Scripture truly comes alive - and the accuracy of His Word becomes progressively clearer in relation to ALL things - including, but certainly not limited to, science, nature, and matters of the heart.
Sitting back and dissecting God with emotional detachment, as if He were a specimen in a lab, with no desire to know Him, doesn't cut it. He is not, and will not be, fully known only through the intellect.
One who persists in willfully resisting His call to seek Him in mind, body and spirit - will remain willfully blind and deaf. And responsible for rejecting His astoundingly costly offer of grace. Our hearts *know* there is something profoundly wrong within us - we alone choose whether to remain hardened to Him.
He didn't lay out the universe, and all that is in it, to just entertain us, but to woo us like a suitor.
We are separated from Him by sin, and He wants us back - by invitation, not by force. Even the most stoic intellectual knows that freedom to choose is elemental to the true meaning of love.
What good does it do to finally arrive at fully defining Him on paper, if we have no desire to be with Him in Person?
Jeremiah 29:11-13 NIV
"For I know the plans I have for you,” declares the Lord, “plans to prosper you and not to harm you, plans to give you hope and a future. Then you will call on me and come and pray to me, and I will listen to you. You will seek me and find me when you seek me with all your heart."
