Welcome to the fray.
As background, I am a former Christian who no longer finds it rational.
I think that beginning of any discussion must begin with your rational reason for believing in the Christian god since you have the burden of proof. Maybe you could start with telling us your rational reasons for (1) believing that a god exists and (2) that this god happens to be the Chrstian god. It is of necessity a two part problem. Let me give a few examples.
Let's say you want to make the argument from design / complexity / creation. The first step would be to show us evidence of design in nature and to show that it could not have come about by natural means. In other words, show us why a god is necessary; where does current theory posit something impossible. You would then need to show us that there was one designer only and why that designer must be the Christian god and not some other god or even advanced aliens.
Perhaps you would like to argue from your own experiences with your god. We would need to be convinced that you were really interacting with a god in some tangible way. We then would need to know why we should accept your experiences, and by extention those of other Christians, and why we should discount very similar experiences of those of other faiths with their gods.
I think that you get the idea. We need to know why we should accept that any gods exist at all and specifically why we can rationally think that your particular god is the one and only. I would expect that rational reasons would exclude discussions based on emotion or faith or circular appeals to one particular holy book and other such logic.
Opps. I did click the wrong place. Too much of a hurry I guess.
Yes, it was meant for theOP.
I think it's fair to say that there's a piont in theism where rationality ceases to exist. That doesn't mean that it's wrong to beleive in a God. Whatever makes you happy, I say. But beyond a point only faith makes any sense in the beleif of God and its accompanying bible stories. Consider these bible contradictions:
PSA 145:9 The LORD is good to all: and his tender mercies are over all his works.
JER 13:14 And I will dash them one against another, even the fathers and the sons together, saith the LORD: I will not pity, nor spare, nor have mercy, but destroy them.

ACT 2:30 Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, according to the flesh, he would raise up Christ to sit on his throne;
MAT 1:18 Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.
ISA 14:21 Prepare slaughter for his children for the iniquity of their fathers; that they do not rise, nor possess the land, nor fill the face of the world with cities.
DEU 24:16 The fathers shall not be put to death for the children, neither shall the children be put to death for the fathers: every man shall be put to death for his own sin.
Several interesting points. I shall try my best to address them. You stated, "Church is like the sandbox of spirituality, it never seems to get to the next level, true understanding of who we are." What do you mean by this, in particular the understanding of who we are?
"The belief systems of most religions seems to be based more on rout, preyer beads, hail Mary's and hosannas and so on." Well, I'm not sure I would agree with that. I've never met anyone who believed that, say, Jesus was the Messiah, the Son of the Living God, because he or she had said a few Hail Mary's or shouted a couple of Hosannas. That seems to be putting the cart before the horse. Rather, it seems that one says a Hail Mary or Hosanna because one believes something like like what's stated above. The action is more of a response to the belief, rather than the belief's cause.
"Most people who call themselves Christians, Jews or Muslims I don't believe have ever read their particular holy book." I can't speak for the other two religions, only my own, and really only a small sub-section of it at that. Sadly, I think this is probably true, though I fail to see the immediate relevance of this on the rationality of the beliefs held.
"They seem to be hand feed only the passages that suits their needs and nothing more." True in some cases, I'm sure, but I think that this might be a bit of a hasty generalization.
"No one religion has a lock on morality or truth, much can be learned from many schools of thought." Certainly it would be arrogant for any person to think that he or she had a complete grasp of truth; we're finite beings. I can't, philosophically speaking, accept the first part of this statement, however. As a Realist, I adhere to the notion that there is a real "way things are" and that anything which contradicts this must not be true. Thus, I'm forced to conclude that either some religious worldview is true (if not, perhaps a naturalistic worldview) and that if one is, then the others must be false since they assert incompatible things. This doesn't mean that my own tradition is the correct one. I may very well be wrong and the Hindu could be right. I don't think that's the case, but I'm not sure I could say that I believe in the Christian worldview if I didn't.
I am an atheist. While I do not believe in God, I respect the rights of those who do. I have no problem with people who pray privately or publicly, as the Vast majority of the desires voiced in their prayers are usually positive and good. I do get tired of religious fanatics who force their beliefs on others, destroying anyone who does not share those beliefs. It makes me sad that so many people seem to need the fear of Hell or the bribery of Heaven to act with moral integrity. I wish that people would search for, learn from, or live by the words of wisdom (found in both fact and fiction) given by so many past and present authors, thus leaving a positive legacy for future generations. I have read the Bible, Book of Mormon, Qu'ran , and Torah. I believe I am a better person from the words of wisdom I have found in these, as well as many other books and writings. I do not need to, nor choose to, act on the violence that is often glorified in the name of God, as well as is found in many other fictitious books and games. We need to like who we see when we look in the mirror. I'm all for anything that helps us see strong, moral, productive, conscientious people.
Human vrs Ghostly impregnation?
Mary was a decendant of David as well. Jesus was a fruit of Mary's loins
The Lord is good to all or just a few?
Mathew 5:45 He causes the rain to fall on the good and the evil.(not word for word)
He is also just to punish the wicked if they choose to remain wicked.
God doesn't shape his goodness or love from what we percieve it should be.
War or peace?
1st your quotes are from two different time frames and situations entirely. In His justice He will defeat the unjust
He extends the oppurtunity for peace to all that repent.
Who was at the tomb?
none of these scriptures contradict. some have more information. There may have been others there that these three accounts did not specify.
i will come back to who's Joseph father?
Is Jesus lesser than, or equal.
When Jesus says I and my father are one, He is not saying equal here. He is refering to a spiritual union. In another scripture Jesus proclaimes we can be one with him, not equal.
