The Bible didn't tell people those things of life in in the time it was written, you even admit to that within your own post. (what I put in bold)
You need more than the word of God? "It is written" was good enough for Jesus and He told the rest of us the same.
Luke 16:31
“He said to him, ‘If they do not listen to Moses and the Prophets, they will not be convinced even if someone rises from the dead.’”
First off, Jesus only said "It is written" when he was directly quoting previous scripture, but he was there with them face to face to address other matters and did. This is why 1 Corinthians 13 specifically indicates that we will have prophecy until we see God face to face.
Jesus was very much in the details of life with the disciples. For example there was when they needed money to pay the tax and it was found in the fish at Jesus direction. Jesus had many a needed word in the moment such as when Martha thought Mary should get up and help her serve but Jesus said that Mary wanted the better part and it wouldn't be taken from her. Meanwhile, there were presumably many faithful Jews in the world who didn't know God was available on earth, and others who even violently opposed the idea. We know that Paul started out as one of the latter.
For me there was a time when I like Paul did not know God could be available so, though I was never violent or argumentative about it. I was faithful for many years not knowing and yet God went out of His way to show my family and myself that there was a lot more intimacy with Him and help to be had. I never put hard limits on God though, which might be what separates you and I now - I let God define God.
Perhaps you are content with so little of God - there were certainly many faithful Jews in Jesus day who never met him and were content to follow God in such a way, but like the disciples, having come to know his deep love and compassion, wisdom, insight, correction, justice, and truth can be available on a personal level, I am not.
Also, you miss the point of the verse you quote, which indicates that miracles will not convince someone who doesn't want the truth, but I never said these things convinced me to follow God. Rather I wanted the truth and to please Him for a long time before He ever showed me a miracle for myself. The miracles were the fruit of a long cared for harvest, not the seeds that made it grow, though actually the Bible also suggests elsewhere that miracles have their place in growing the faith of new believers.
1 Corinthians 2:4-5 NASB1995
"[4] and my message and my preaching were not in persuasive words of wisdom, but in demonstration of the Spirit and of power, [5] so that your faith would not rest on the wisdom of men, but on the power of God."
