Supposedly, if you seek, you will find. I have been poking at Christianity for many years and I have read a whole list of books from both sides. I have read the New Testament in full and all 4 Gospels multiple times. I have read Mere Christianity, Case For Christ, A Skeptics Guide To Faith amongst others. I have also read other critical books such as The God Delusion, The Rise of Christianity, and The Evolution of God. I have been open to Christianity and have no hostility towards spirituality. I have attended church semi-regularly. But, the more I learn, the more the following seems clear:
1) The Bible is not historically or literally accurate. There are parts that are likely based off true events and true people, but I would say the majority is either exaggeration, allegory, myth or poetry.
2) Jesus is not the literal "Son of God". I do not know what this means outside of some sort of metaphorical context.
3) Church sermons do not depend on the historical truth of the Bible. Many sermons that I have heard are simply literary analysis of a passage which is independent of the historicity of the passage. For example, just this past Sunday, the pastor at my church preached on Mark 5:21-43 in which Jesus heals a bleeding woman and restores a dead girl to life. He used this passage to talk about spiritual healing in our lives and even mentioned how the writer of Mark set up this story in such a way to contrast Jairus and the bleeding woman. The way he spoke made me realize that the historicity of the passage was irrelevant. You could provide the same literary analysis and spiritual application by reading any myth.
4) Christianity is a 2000-year old evolving misunderstanding; a group of conflicting opinions on God, Jesus, spirituality, and paganism. It was warped so thoroughly by the Roman empire, that it is difficult to try to reconstruct what the "original" Christianity looked like. We look at Jesus, Paul and the Bible through a 2000-year lens of history with all the associated theological and historical baggage.
You don't seem familiar with Catholic theology. Catholicism is Christianity. Jesus only started one Church, and most Christians belong to this Church.
If you want to understand Christianity you need to study Catholicism.
I recommend you read the first couple of chapters of the Catechism. I think it will resolve many of the issues you have with Christianity.
You can check it out here. Here's the beginning:
I. The life of man - to know and love God
1 God, infinitely perfect and blessed in himself, in a plan of sheer goodness freely created man to make him share in his own blessed life. For this reason, at every time and in every place, God draws close to man. He calls man to seek him, to know him, to love him with all his strength. He calls together all men, scattered and divided by sin, into the unity of his family, the Church. To accomplish this, when the fullness of time had come, God sent his Son as Redeemer and Saviour. In his Son and through him, he invites men to become, in the Holy Spirit, his adopted children and thus heirs of his blessed life.
2 So that this call should resound throughout the world, Christ sent forth the apostles he had chosen, commissioning them to proclaim the gospel: "Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you; and lo, I am with you always, to the close of the age."
4 Strengthened by this mission, the apostles "went forth and preached everywhere, while the Lord worked with them and confirmed the message by the signs that attended it."

3 Those who with God's help have welcomed Christ's call and freely responded to it are urged on by love of Christ to proclaim the Good News everywhere in the world. This treasure, received from the apostles, has been faithfully guarded by their successors. All Christ's faithful are called to hand it on from generation to generation, by professing the faith, by living it in fraternal sharing, and by celebrating it in liturgy and prayer.
