If there be a messenger with him, an interpreter, one among a thousand, to shew unto man his uprightness: Then he is gracious unto him, and saith, Deliver him from going down to the pit: I have found a ransom. His flesh shall be fresher than a child's: he shall return to the days of his youth: He shall pray unto God, and he will be favourable unto him: and he shall see his face with joy: for he will render unto man his righteousness. (Job 33:23-26 KJV)
Many today's teenagers have trapped themselves into depression, saddness, and rejection. Most young people would like to be adults because the influence of media teach them how they should live their lives. MTV is the most influence in their young lives today. Yet, we, as adults, sometimes let our media teach our youngsters how they should live. For example, some Christian adults allow children to read and watch on Harry Potter, which it contains witchcraft and other pagan rituals. Or Chroncle of Narnia, which it was originally written by one of the greatest preachers, which it has mixture of Christian salvation and Pagan ritual. Although I watched the movie before, I would not recommend for any pastor to use it as a sermon tool to bring people into Jesus Christ.
Job 33:23-26 tell us that God has shown favor to youths and we should remind ourselves what was to be like in that ages. God is always looking after His young children. We should not push themselves immediately to adulthood. Remember when children tried to come to Jesus and His disciples rebuked them. However, Jesus rebuked His disciples and questioned why they tried to block little ones from Him. In Matthew 19:14 says, "Suffer little children, and forbid them not, to come unto me: for of such is the kingdom of heaven."
Do you like to become child of God? Give your whole life to Jesus by admitting that you are sinner and ask Him forgiveness; and then ask Him to come and live in your life. That's simple and there's no formula to add into your communication with God. Then I would strongly suggest for you to find a local church, where you can receive strong Bible teachings that would benefit your new life with Jesus Christ and can find some new Christian friends who can further help and encourage you in daily basis.
