Let no one despise or think less of you because of your youth, but be an example (pattern) for the believers in speech, in conduct, in love, in faith, and in purity. ~1 Timothy 4:12
There are a lot of things that us "younger" people can't do, like the "older" people can. You have to wait to be sixteen to get your driver license, some states it's fifteen. You must be eighteen to vote and officially be considered an adult... but truly it's not until you turn at least twenty-one, that people actually see you as an adult.
High School graduation recently just passed. So many young people getting ready to start a new adventure in their life. So many of them have waited for this day, to finally be considered an older person and go by their own rules. If they only knew...
God doesn't wait to give you a purpose when your considered older. He set it out the day you where born. Everyday you have a purpose! Stand strong and believe in yourself... don't change for the world. Continue to grow in God's love and walk in the grand adventure He has laid out before you everyday.
Being young is nothing to frown upon. Many heroes have come from the youth... David being one of them. Don't grow up too fast, enjoy the you now.
