Do you stand out in a crowd? If you do, that's fine; but be careful, because the next question is kinda loaded: Why do you stand out? If it has anything remotely to do with the notice that 'It's all about you!' or 'It's your world !,' then you do not get any points for that answer (actually, you lose a few). Now, there's nothing inherently wrong with drawing the attention of others. The problem most often arises, however, in the identification of just who it is that's blowing the proverbial horn. If the person is quite getting looked at at the same one who's generating the noise … again, points deducted.
Let's take the Lord Jesus, for instance. Now there's a Man who created a stir wherever He went. Well, that's not fundamentally accurate. It's much more on target to say that where He went, a stir was created. He did not intentionally do things to draw attention to Himself. He just administrated the Kingdom of God to the poor, sick and afflicted around Him (Luke 11:20), and attention came to Him. He never tried to make His voice heard or cause a stir in the streets (Isaiah 42: 1-3; Matthew 12: 18-20); neverless, stirs followed Him around. As a matter of fact, on several occasions, for logical reasons, He actually tried to keep His exact whereabouts unknown to the general public (Matthew 9: 30-31; Mark 1: 44-45). Jesus just let the Light that was in Him shine. In other words, people saw His good works and were automatically drawn to Him (Matthew 5:16).
That's the very example that we, as children of God's Light, are supposedly to be following (Ephesians 5: 8, 1 Thessalonians 5: 5). The works that Jesus did we're supposed to do, and even more (John 14:12). And, if we did, do not you think there'd be a stir around us, too? I mean, let's face it; if you walked into a church and busted up a perfectly good funeral by raising the dead person, there's going to be a ruckus. And after everyone stops running, you're going to get interviewed!
But that will not be blowing your own horn, it'll be the light of your knowledge of God's glory in the face of Jesus (2 Corinthians 4: 6), and that same Light will be manifesting itself up and through you. The crowds will see the good works you do and glorify God your Father (Matthew 5:16). You will not need to try to exalt yourself; the Lord will take care of that for you. He will lift you up (Psalm 3: 3), and you will not have to worry about that painful fall that inevitably comes after prideful self-advertisement (Proverbs 16:18; Matthew 23:12; 1 Peter 5: 5- 6).
The Light we've been given is not just for us to see by. It's as much (or even more) for those around us, those who are hurting, afflicted and stuck in darkness (Matthew 5: 13-15), and so it should always be on. As the old song goes, "Let it shine, let it shine, let it shine!" Under those circumstances, it's just fine to stand out in the crowd. You can be sure that someone around needs you to.
