Don’t let anyone think less of you because you are young. Be an example to all believers in what you say, in the way you live, in your love, your faith, and your purity. 1 Timothy 4:12 (NLT)
Being young doesn't disqualify you from being an example. Another way to say it would be, being young doesn't disqualify you from being an inspiration to someone else. We have all been inspired by young and old in a variety of areas and living as a Jesus Follower is no different.
In this passage, the apostle Paul is writing to a young Timothy; actually, Timothy was most likely 30 years of age or older. During that time and in that culture, an individual wasn't considered experienced or a professional in his or her craft until at least 30 yrs. of age.
No matter the case, Paul's point to Timothy is this, You can be an inspiration and example of Jesus regardless of your age. Jesus at 12 yrs. old challenged and inspired the older, religious teachers of His day. And if Jesus lives in us, His Holy Spirit will inspire and encourage us and and those around us . Remember, it's not you living like Jesus, It's Jesus living His life with His grace and power, through you.
So don't worry how old you are. Let the light and life of Jesus shine regardless of your age. He longs to inspire others through your obedience to Him.
Lord Jesus, help me not to believe the lies that tell me I have to wait until I'm older for my life to have an impact for You. Today with your grace, I ask You to use my life as an example for all I will encounter. Amen
