I became a Christian after over 2 years of hearing the Word of God through a friend, so it didn't happen immediately. I come from a Catholic family, although I never really read the Bible until a Christian friend invited me to her church.
Last year, after some changes in my life, I decided to start reading the Bible on my own again...my parents didn't approve of me going to a Christian church so I learned on my own, in my room, reading the Bible online and studying it. I am now able to attend a church, but it wasn't that way at the beginning.
Let me tell you this, since we humans are flesh and bones, and the flesh goes against the Spirit, there will be A LOT of times when we won't like what the Bible says

. Especially if that means changing your life radically, and that's exactly what Jesus does, He changes your life radically. He lets you know than life is not about ''ME,ME,ME'' and more about serving Him and serving others. Humbling yourself can be the most painful experience in life, and that's exactly what God wants from us.
Another thing I would like to add is that not all the churches have the true gospel...I feel horrible to say this as Christian because we are supposed to be the light of the world, but that's why the Bible says ''test everything'' so you won't be deceived into false teaching.
The reason why I'm a Christian and I will continue to be a Christian for the rest of my life is because even though man can fail, and I myself can and will fail, God won't stop being faithful. This verse expresses my sentiment very well:
True, some of them were unfaithful; but just because they were unfaithful, does that mean God will be unfaithful? Of course not! Even if everyone else is a liar, God is true. Romans 3:3-4
