You are the light of the world. A city situated on a hill cannot be hidden. No one lights a lamp and puts it under a basket, but rather on a lampstand, and it gives light for all who are in the house. In the same way, let your light shine before men, so that they may see your good works and give glory to your Father in heaven. - Matthew 5:14-16 HCSB
Whether we want to be or not, whether we like it or not, all of us are examples. The question is not whether we will be examples to our families and friends; the question is simply what kind of examples will we be.
What kind of example are you? Are you the kind whose life serves as a powerful example of righteousness? Are you the kind whose behavior serves as a positive role model for young people? Are you the kind whose actions, day in and day out, are based upon integrity, fidelity, and a love for the Lord? If so, you are not only blessed by God, you are also a powerful force for good in a world that desperately needs positive influences such as yours.
So, as Corrie ten Boom advised, "Don't worry about what you do not understand. Worry about what you do understand in the Bible but do not live by." And that's sound advice because our families and friends are watching.
