“At the same time the Lord spoke by Isaiah the son of Amoz, saying, ‘Go, and remove the sackcloth from your body, and take your sandals off your feet.’ And he did so, walking naked and barefoot.”
Sometimes, the Biblical message is so important it is presented along with an unforgettable illustration. This is one of those cases. Isaiah’s warning, regarding the coming destruction of world powers by Assyria, was so critical, that he undressed and walked the streets of Jerusalem to declare it. While I do not recommend that exact approach, and we recognize that the true power behind the Gospel is the Gospel itself, we might want to at least consider how we might better illustrate the truths of Scripture, as we seek to share them with others.
If you are involved in teaching the Bible, it is important to use illustrations that are age and culture appropriate. Things that interest adults might not catch the attention of children, and things that excite children might be a bit crass for the elderly. It is the message of Christ which is most important, but a little creativity in expressing it can prove to be extremely helpful. A basic approach to teaching the word of God is to read the text, explain the text, illustrate the text (this can be done with other Bible passages or personal experiences), and finally, applying the text.
One more thought, If you are involved in street witnessing, one of the most effective tools in witnessing to others is to ask them questions about themselves. If we take a few minutes to get to know someone, we will find we are more effective in addressing the issues they are facing, and it will cause us to truly care about them and their situation.
