"For I am not ashamed of the gospel of Christ, for it is the power of God to salvation for everyone who believes, for the Jew first and also for the Greek." - Romans 1:16.
Are you ashamed of the gospel? Does your life prove otherwise? If you were put on trial for being a Christian would there be enough evidence to convict you? The apostle Paul lived his life unashamed of the gospel because it was that gospel that set him free and he couldn't help but tell others about it. That's what happens when Christ truly changes a person; he can't help but tell the people around him about what happened. The gospel isn't something that is meant to be kept inside Christian's hearts. To be honest, it's quite the selfish mindset to not tell others about the freedom we experience in Christ.
Get out in the community and preach Christ unashamedly to those who are dying and on their way to Hell as you read this. I feel as though there is a lack of urgency in Christians today to give the gospel of Jesus Christ out. Is it because we are ashamed of the gospel?
