The Bible says in Romans 1:16,"For I am not ashamed of the gospel of Christ, for it is the power of God unto salvation to every one that believes...." Sin has become so bold. I have noticed how bold people in the world are after they become intoxicated with alcohol. They are likely to say or do just about anything. We as believers need to have the same boldness for the gospel of Jesus Christ. You do not need to be ashamed of what Jesus christ has done in your life.
