God saves people individually one at a time. We focus our attention on the individual. Reaching them wherever we may find them. This means that often we will be sharing the soul saving, life changing Gospel inside and outside people’s homes. The church house is not the only house where people need to hear the Gospel.
There are times when the street and the market place is the best place to preach the Gospel to people. When Paul was in Athens, he challenged people with the truth of God’s Word wherever he found them. This meant that he preached to them when they went to market as well as when they lounged in their homes.
