SkovandOfMitaze made a fair number of points that I would tend to agree with also.
However, I might back off on the fine-tuning a little. Look at it this way. Suppose we find a way to mix a bunch of chemicals together in a flask, shake it, and a fish comes out. Does it really mean we don’t need God?
Suppose further that we could show (somehow) that there were a multitude of combinations of the various constants that would render some sort of viable solution where intelligent life could form? Does that mean we don’t need God?
Would not such findings be even scarier because now, we really think we are God? Yet you know just as well as I do just how rotten we human beings can be without the holy spirit to still our impetuous mouths. Even the best of us, even those who really try to follow Jesus can screw up big time. We can rashly lose our temper, we can be petulant, we can judge people cruelly, we can think we know people when we really don’t. We believe in our technology. We’re hardly different from the people who built the tower of Babel. Our construction can even bring us close to the heavens than even in that time, and google translate is often sufficient these days that we can understand the garbled translations it generates.
It’s probably good if God makes it so we are too thick to figure out how life came about so we don’t become even more insufferably overflowing with hubris about the power of our technology as “the answer” to life truth and everything.
Look more to the reasons for faith. Isn’t faith about doing what is right even when it will cost you severely? Faith is about being confident in God in the times when you might lose your job, maybe ruin your hard-earned career because you listen to Jesus instead of listening to power and authority who have gone astray.
Consider this point from John 12:37-42
37 Though he had done so many signs before them, they still did not believe in him, 38 so that the word spoken by the prophet Isaiah might be fulfilled:
“Lord, who has believed what he heard from us,
and to whom has the arm of the Lord been revealed?”
39 Therefore they could not believe. For again Isaiah said,
40 “He has blinded their eyes
and hardened their heart,
lest they see with their eyes,
and understand with their heart, and turn,
and I would heal them.”
41 Isaiah said these things because he saw his glory and spoke of him. 42 Nevertheless, many even of the authorities believed in him, but for fear of the Pharisees they did not confess it, so that they would not be put out of the synagogue; 43 for they loved the glory that comes from man more than the glory that comes from God.
Whereas generally, we read this passage to be about people rejecting Jesus because they worship the world, at that time, the “synagogue” was an essential part of a person’s life. Today, going to church is a choice and hardly something that demands a great sacrifice. The modern “synagogues” are the institutions that symbolize success in modern society. If you are fired from your job, or you lose an election, in many ways, this is the synagogue for us now. Like most sin, it starts with the little things and graduates. Eventually, if you resist the powerful in doing evil or say something that superiors don’t want to hear, and you can be thrown out of these modern “synagogues”.
Isn’t the real point that if we actually accept Jesus, we will do what is right – even if it costs us dearly. Our struggle is to learn to trust in God, not to revel in worldly blandishments or quarrel about things that none of us can really answer. We want to do what is right in the world.
It is there you should be looking for Jesus. Although fine-tuning and evolution are very challenging problems to understand, they are comparatively easy questions. Yet, if God used evolution, what can we say? If God made a “world” where all multiverses (if they exist) could have different constants and in every one of them, intelligent, sentient beings could evolve, I don’t think that tells us anything. It is living out a life of repentance that matters and fine-tuning and evolution (true or false) makes no difference to that. Following Jesus is a way to say that you desire to do what is truly right from that 30000 ft perspective of God’s eyes, not your own. [Maybe, in terms of scale, that should be the astronomical or multiverse perspective of God’s eyes.]
by grace we proceed
