1 Timothy 4:12 Don't let anyone look down on you because you are young, but set an example for the believers in speech, in life, in love, in faith and in purity.
There have been many times in my life when I felt inferior and out of place because I felt young and inexperienced. At lest that is how I saw myself. This scripture reminds us that age and wisdom do not necessarily go hand in hand. Often, our youth and innocence can be refreshing. Like a child that comes to God without reservation and all of the distractions that more years and responsibilities can bring.
Don't discount yourself. Be the example. In what you say and do. Let your words and your actions be clear and up-lifting. Share your affection and your faith. Be genuine, authentic and pure: undefiled.
Sometimes the more miles you have on your life the more cynical you get. While you are young(and you are!) embrace your youth. Stay close to the Lord and live right. Be a good example...better yet be a God example! And when you get older, you can remain wise!
