Children are important, no matter what anyone says. Has someone ever told you "I'm and adult and I couldn't do it, what makes you think you can do it?"? That, "You're a child, you can't do much."? I have and this is what the bible says about it:
"Don't let anyone look down on you because you are young, but set and example to believers in speech, in life, i love, in faith, and in purity." ~ 1 Timothy 4:12
Be an example. Don't just back down because someone told you that you couldn't do it. Be the hands and feet of Jesus.
These verses also go along with that:
"Some people brought even their babies to Jesus so he could touch them. When the followers saw this, they told them to stop. But Jesus called for thechildren, saying, "Let the little children come to me. Don't stop them, because the kingdom of God belongs to people who are like these children. I tell you the truth, you must accept the kingdom of God as if you were a child, or you will never enter it." ~ Luke 18:14-18
Basically what this is saying, is that you don't get into Heaven by being very skeptical. You have to think like children when it comes to the Bible, and believe everything you read. You just can't think like an adult when it comes to reading the Bible.
I hope this first chapter was helpful.
