Isaiah 20:2
“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.

Isaiah 6 is perhaps most well known for what Isaiah saw. He records, in the year of King Uzziah’s death, he had a vision of the throne of God. He describes how he saw the Lord enthroned and surrounded by angelic beings, who ever live to give Him praise. What perhaps, is sometimes missed, is what Isaiah heard. He records hearing the voice of God in two distinct ways.
Over the years, I have met Christians who seem crippled by uncertainty. They struggle with every decision they make, because they don’t seem to be able to determine God’s will. It is true God has a perfect plan for our lives, and to understand it, we must get alone with Him, and listen to His still small voice. But it is equally true, God has already laid out much of His will for us in the pages of His Word. In the text before us, we learn what we should be doing with our mouths.
The Northern tribes of Israel reached the zenith of their strength under king Jeroboam II. Here we are given insight into the secret behind their success:
Philip was one of the men selected to serve tables at the church in Jerusalem. Now we find him heading out to Samaria as a missionary and winning many souls to the Kingdom. His ministry became so effective, it drew the attention of the apostles, who came to aid him in discipling those who had been saved. As quickly as he arrived in Samaria, Philip leaves. God calls him away from the masses, to reach an individual with the message of salvation through faith in Christ. After a muddy baptism in the desert, he headed out once again, this time making his way to Caesarea, where he settled down and raised a family of followers of Jesus. 
Sadly, the world has no shortage of those who are in need of Christ. Our population has reached the seven billion mark. Seven billion souls walking this planet, many of whom do not yet know Christ. We recognize certain places in the world as being unreached. Places where many, or even most, of the citizens are yet to hear the good news of salvation, through faith in Christ. We need to pray, send, and provide for those who go to the uttermost parts of the earth with the Good News of Christ. However, we cannot neglect to remember the many unreached souls in our own backyard. Here, in Luke 10, as Jesus sends the seventy, we have some practical instruction on how to reach the lost.
In the synagogue in Capernaum, Jesus encountered a man with an unclean spirit. While there is no way of knowing what lifestyle he had lived which led to his condition, we can surmise from other accounts of dealing with demons, he was living in great darkness and difficulty. Whatever turmoil he faced, the solution was encountering Jesus. What the world could not do, Jesus did with seven simple words,”be quiet and come out of him.”
