One of the most powerful words spoken is the word 'look'.
If you were to stand up and blurt out 'LOOK' among a group of people, just about everyone will turn their head in the direction you are pointing them to, in an attempt to see what's going on.
No one is getting paid or forced to look. They are simply looking because they were asked, and probably because everyone else is looking as well.
When witnessing to this lost and dying world, instead of fighting or demanding compliance, why not simply ask someone to 'LOOK'.
It might go something like this: "This world has been hiding a powerful truth from you. I'd like to show you what it is. Do you have a few minutes to look at this truth with me?"
You can then go on to present to them the saving gospel of Christ.
LOOK! It's a simple word, that packs a lot of punch.
