Like the others above me, there are so many reasons for my faith in God and Jesus.
Firstly, it's this sense of love. I feel loved when I think about God and Jesus. Before the age of 14, I was raised in a Christian family, but I had never truly felt connected with God or Jesus. I just kind of felt like I was floating around. I didn't really give much thought to the world around me, why it was there, or why I, myself, even existed. But, I kind of felt an emptiness. I kind of wanted answers, you know? The world and us as human beings had to come into existence somehow, so there must be an answer as to why. But, a couple years back, I went on a trip to California that had a youth pastor as a speaker for us. He talked about when he first found faith, he was in Mexico with a serious illness, and as he walked down a chapel hall, something just hit him. Before knew it, he fell on his knees and started saying, "I love you. I love you, God." The same situation happened to me similarly. At the time, my brother had been heavily involved in drugs, and I was beginning to fell numb, as he had left the house in a very angry manner, leaving the family in a mixed up state. But, when I went to a small youth group in Fountain Valley, I felt something burn my chest-- just like the youth pastor had said. I sobbed, and before I could be embarrassed or hide my crying, I just wailed. I had stayed that way for a good 10 minutes, just saying, "Please help me. Oh God, please help me!"
I guess, on the note of that, I've noticed that when people get into their most desperate moments or moments of utter sadness, confusion, or anger, they speak. They talk, as if they are talking to someone. I feel it's an outreach towards God. I think people all want someone to be there, and I believe there is someone there. It almost seems...natural, although I know that may sound weird to some people.
Secondly, it doesn't feel like I'm just talking to air. I think a lot of people may think that when they discuss Christian faith with others, but for me, it's simply not true. It really does feel to me as if someone is listening, taking note of all my sadness or joyfulness. I feel like someone loves me and is hanging on my word and giving me guidance in my life. It doesn't feel silly or forced. It just feels like... like talking to someone you love SO, SO much, and you just can't help but tell them about everything. There are no secrets, no desires to hide yourself away. There's just this intense feeling of someone looking inside your soul, searching for YOU, and loving you how you are, despite your imperfections.
Thirdly, I don't think I could personally bring myself to believe that, after death, there was nothing. I guess I should be honest in my thoughts in saying that I don't understand why. To me, it just seems as if there are too many people, too many lives, and too many individuals so different in who they are that are living now and that have already died. There are just too many people for them to all just become nothing. It feels like we're too special, we're too precious, too detailed, and too loved to just become a resource for the Earth. In all the complexities that embody the human race, it almost seems impossible that science or evolution could possibly explain it all: why we're so different, why we think differently, why we have different personalities, why we love, why we hate, etc. In all the abstract things that we are, I can't see how there could be anything else. I don't want to believe that I'm living to eventually become nothing. Actually, I refuse to believe it. To be honest, I believe you are too important. And I believe the only reason we'd be so intelligent, and so emotional and so vulnerable is because we are so loved by someone who is ready to give us eternal life and love us forever.
Hopefully, that gives a little bit of insight about my view on my faith.

I hope you do well, and God bless.
