Watnee, within 1 hour you started a thread declaring yourself an atheist and citing observed behavior by Christians and differences of beliefs within the Church and then you posted this. If I hadn't read your other thread, I might be of the understanding that you were a Christian posing this thought to others in the faith.
People come to faith in different ways, but by hearing the Gospel is how people generally come to know the Lord. Some read the Word and come to believe. Regardless of how they come to faith, they are called to faith. Everyone needs to study the Word to solidify their understanding. They are given the ability to find it within themselves to accept that which on the surface is unacceptable. Some people are called and choose not to accept it. That's very sad. I believe it comes from evil within that doesn't want to be subordinate to any authority, especially God.
If you take the origins of the believers, you have to put yourself in the place of those who were present when claims of Jesus resurrection were being circulated. If these were false claims at the time, surely people would have stood up and said, "No! That's not true! I was there, and what he's saying is not true!" They were making claims that could have been refuted by other eye-witnesses.
Also, we have the martyrs who died rather than reject what they witnessed and knew to be true. They didn't read something that had been written, believe it, and carry it out to their death. They witnessed it and refused to back down when faced with death. But Muslim martyrs who also die for their belief. What about them? This is very different from actually witnessing it or not witnessing it and dying for the Truth. These people knew first hand whether they were telling the truth about something they claimed or not. Who would die for that? I say, no one. If I was telling a lie that I knew was a lie, I wouldn't die defending it. Would you? But if I was convinced by something I simply believed without witnessing it, I might.
In response to your other post (I think it was yours - there were a few recent ones), we can't judge the legitimacy of the Truth by man. We are flawed in the flesh and will behave in ways not acceptable to the Lord. There are also people to don't truly listen to God and understand His Truth. Differences that we have in our various doctrine stem from misunderstandings while in our human condition. Most of these are not "salvation issues". While they are different interpretations, our salvation does not hinge on them.
I pray you re-evaluate your stance and seek the Lord. If you honestly seek Him with your heart, you will find Him. He WILL reveal Himself to you as He has to me and countless others.
Blessings,
Mike
