A lot of people feel that it's someone else responsibility to tell people their need of salvation. That's not true. It is the responsibility of every born again Christian to tell whoever they come in contact with that they need Jesus. We were not saved to sit around and do nothing while people in our towns are lost and going to hell.
When we stand before God and He asks us why we didn't witness when we had the opportunity, what will we say? Everyday we must ask the Lord if there is anyone He wants us to visit or to speak to. If there is, the Holy Spirit will reveal to us who He wants us to minister to. What are you doing in your town? Do the members of your family know they need to be saved? Can you say with the Apostle Paul, "I am pure from the blood of all men?"
