Jesus' last command to us was to go and preach the gospel to every creature. Even after accepting him in our lives many fear to proclaim the gospel to others. God told Ezekiel, if he refused to warn people to turn away from their sins, their blood would be upon his own head. It is sin and selfishness to know the truth and not share it with others that are perishing. We don't need a raised platform to preach the gospel, rather to determine ourselves to talk to people around us.
