You may not like it but I started believing in them when I was little because my parents taught me. However, it was because my parents taught me to pray that I began to feel the love, peace, joy, guidance, and comfort in return.
Many would scoff at me, but I have actually recieved direct answers that are beyond denial. These helped me in my youth to stay faithful but I still had my doubts.
Much of the attitude of my parents helped me approach religion and my understanding of God, and only through time have I learned much for myself and come to appreciate that what they taught me actually is the truth.
I don't blame you for being upset sometimes, but when you start in your beliefs you need to realize that in the begginning your motives aren't going to be as pure as you had hoped. If you want to know God, then don't bite the hand that feeds you. A loving parent does everything in their power to teach their children to obtain the true joys of life, yet if a child outrightly rejects everything from the parent then how can the child come to know its loving father or mother? The same is true with god.
I would give you this peace of advice. In an existence where joy and pain, love and hate, etc... exist, trust that the greatest things, those which are good rule over all. Otherwise, pain would not allow joy to interrupt its dominion, light would not be allowed to penetrate the darkness at a whim, and love could never find place to enter our hearts. Happiness is the design of our existance, yet to exist as we do means we must have choice. To think and to act requires choices, otherwise we could not "taste" the sweet because we had never known bitterness. To fully appreciate joy, one must appreciate the price to obtain it, just as with peace, a universal ideal among humans that many have paid dearly for, and our generation takes for granted.
When wanting proof for everything realize that science deals with the senses and relies on them. Yet science does not come close to explaining WHY we feel, why we sense, and above all why we have emotion, yet we know these things are real. Science cannot explain the identity of the soul, and even if they should find some neural network to label conciousness it simply does not explain the innate fact that we exist and what we feel matters, and that for some reason we can feel (utimately what is feeling what).
I will also give you this analogy as one who believes in God and Jesus Christ.
I was thinking about it today actually. Suppose you knew someone who grew up in the middle of Saudia Arabia or some completely desolate region devoid of trees and rain and had never experienced either. Think of the sound of rustling leaves in the wind, or the quiet roar of countless raindrops falling to earth. Now try making those sounds accurately just by using your voice. Despite your best efforts, and a almost tangible knowledge of those two sounds you could never give your friend that experience by simply relating it with your meager vocal chords.
Well, in a feeble way I tell you that God does exist, and that Jesus Christ is His Son.
In a universe full of the often bitter equations, and demands of natural law, God (the overseer and Lord of all) sent His Son to provide a way for us to fully enjoy our existance, and grow and conquer over our struggles. Jesus Christ is the answer to the infinite costs and demands of nature as only God could calculate and pay. He has allowed us the opportunity to learn to experience and to seek after good things, if we so desire them. But rest assured He lives, and makes it possible to be truly happy. It isn't easy, but I know from experience it is possible, and worth it.
He lives, and you are his child. How can I prove it or completely describe it? I cannot, but I know you can experience it for yourself because I have experienced it and so have millions upon millions of others. (sounds kinda like the scientific method...funny huh...)
A song I know goes thus:
"Heavenly Father, are you really there?
And do you hear and answer every childs prayer?
Some say that Heaven is far away, but I feel it close around me as I pray.
Heavenly Father, I remember now, something that Jesus told disciples long ago.
'Suffer the children to come to me'
Father in prayer I'm coming now to Thee."
"Pray, he is there, speak, he is listening,
you are his child, his love now surrounds you.
He hears your prayer, he loves the children, of such is the kingdom of Heaven."
What more can I say besides keep an open mind and seek out the best things, the things that are good simply because they are self evidently so.
If you so desire, I am a member of the Church of Jesus Christ of Latter-day Saints, and I would offer this link as a place to visit in your search. This site provides concise overviews of my own beliefs, consider them along with any others you encounter if you so desire.
God loves us, and will allow all of us the opportunity to come to know Him, so don't be afraid to look, listen, taste, and learn. Choose the good things.
