Allow Jesus to reign in your life above all things. Lift Him up in every moment that you are around different people.
1 Peter 3:15,16 (KJV)
15 But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear:
16 Having a good conscience; that, whereas they speak evil of you, as of evildoers, they may be ashamed that falsely accuse your good conversation in Christ.
