My current state of composure is due to a manic/depressive mood swing. If you'll pardon my inconsistency, I'll be more succinct.

I believe as a result of the evidence of history, testimony, and the overwhelming inability to disprove the Bible, that it is true and the Word of God Himself.
Because of this, I believe what the Bible says about sin, right, wrong, truth, and what it means to follow the example of Jesus Christ, (being a Christian).

I still doubt. I shouldn't, but I do. I still sin and disobey God. I shouldn't, but I do. But the Bible also says that if I sin, I have an advocate with God, Christ Jesus the righteous. And that if I confess my sin, God is faithful and just to forgive me of my sin and cleanse me from all unrighteousness.

Faith is not the absence of reason, it is the substance of things hoped for. For without faith, there is no hope in what is not, or what is not yet come. Faith proves the existence of hope by itself and vise-versa. Reason is finite and based solely on logical(critical) thinking. But even reason does not understand emotion and metaphysical elements of human existence.

The spiritual side of life is the equal and opposite reaction to the physical.

I don't reason faith by merit, but rather by choice. I don't regard my faith as an escape route from Hell: for the price of my faith was a high cost to Christ and myself. My doubt is humanity speaking in frailty to the power of God. I limit His ability in my life by my lack of faith.
