(Pro 10:21 KJV) The lips of the righteous feed many: but fools die for want of wisdom.
One of the points made to push people to witness and evangelize is that you may be the only source of contact the non-believer has with the gospel. I think there is a bit of cotton candy theology mixed in with that. Cotton candy is formed by taking a small amount of sugar and adding a lot of air to make it look a lot bigger. I think it is safe to say that just about everyone we come in contact with has been touched by either the gospel or some kind of pre-gospel presentation. Notice in the verse that there seems to be plenty of wisdom available but the fools are not accessing it.
Think about the presentation points. Most traditional Christmas carols have the redemption story worked in. We have holidays that are based on the concept of saints. Valentine and Patrick come to mind. Many cartoons strips make reference to spiritual things. The information is out there, just ignored or deliberately avoided.
So? Be ready to make a defense of your hope as Peter tells us. Don’t get trapped into thinking it all depends on how many verses you have mastered in the right order. They need to be willing to listen and prepared by the Holy Spirit.
