say this prayer:
"Dear God, I know that I'm a sinner, and I know that you love and care for me deeply. I believe that your son Jesus Christ died on the cross for me. Please forgive my sins and guide me in the right path. I love you with my whole life, my whole heart, my mind, body and soul. Please mold me into a new person so that I may love you as you love me, and love my neighbors as myself. In the name of Jesus I pray, Amen."
After saying this, take a quite moment to reflect on who you are, what's good about you and what you need to change. Know this; you don't really put your "hope" in God. You trust in him, and hope comes as a second thought. But with God, you can't go wrong, so you can always put your trust in him no matter what. And just hope for the best. And make sure your church has an excellent program too. Very few churches are efficient in their teachings.
Lastly, read your Bible, especially the Book of Psalms. It'll teach you a lot about what you want to know. I know this is long, but I'm a young man trying to find God myself. As (so called) Christians, we have to pray everyday and encourage each other. Thank you for asking, and God bless.
PS: Take 1 step toward Him, and He takes 2 toward you. Soon, He will find you before find him.
Holy Bible (preferably the King James Version).
