I believe God wants people to believe in Him. But I also believe that God wants us to believe in Him through faith. I believe this life is a trial that the goal is to obey God in all things even if there isn't any supporting evidence in front of our faces. To me the idea that God would coerce people to believe in Him, by using some form of irrefutable evidence, goes against what I believe God's plan for us is.
Yes there are miracles, but the purpose of miracles isn't to prove to those who don't believe but to support the beliefs of those who already believe.
If God prefers faith to providing tangible, firsthand evidence, then we need some explanations for the following Scriptures:
John 2:23 Now when he was in Jerusalem at the passover, in the feast day, many believed in his name, when they saw the miracles which he did.
John 3:2 The same came to Jesus by night, and said unto him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him.
John 6:2 And a great multitude followed him, because they saw his miracles which he did on them that were diseased.
John 10:37-38 If I do not the works of my Father, believe me not. But if I do, though ye believe not me, believe the works: that ye may know, and believe, that the Father is in me, and I in him.
And here is another Scripture that shows that many people were very impressed with the miracles that Jesus performed:
Matthew 4:24 And his fame went throughout all Syria: and they brought unto him all sick people that were taken with divers diseases and torments, and those which were possessed with devils, and those which were lunatick, and those that had the palsy; and he healed them.
In the NIV, the book of Acts basically says that the disciples went about confirming the message of his grace by performing miracles. That is quite odd if Jesus had already performed many miracles, and had been seen by hundreds of people after he rose from the dead, and if the Holy Spirit had come to the church. Why were even more confirmations needed? We need tangible, firsthand confirmations much more today than people did back then because there aren't any still living eyewitnesses around like there supposedly were back then. Why would Jesus say "O ye of little faith" and then give in to some stubborn skeptics who demanded tangible, firsthand evidence? Jesus supposedly criticized Thomas for wanting tangible evidence that he had risen from the dead, but yet Jesus was perfectly content to perform miracles before some stubborn skeptics who were not convinced by his words alone.
If a God exists, and he wants people to have faith, he could easily directly communicate with everyone in the world without the use of written texts, whether tangibly, spiritually, or both. That would be much more effective than using written texts.
If God wanted to spread news about Jesus all over the world, why didn't he want to spread news about himself all over the world during Old Testament times? The correct answer is that the God of the Bible does not exist, and the Jews appointed themselves to be God's chosen people.
