Romans 1 : 16

Romans 1 : 16 - "For I am not ashamed of the gospel of Christ, for it is the power of God to salvation for everyone who believes..."
"Christ and His Gospel will always be spoken against. If you know a gospel which is approved by the [culture] and patronized by the learned, that gospel is a lie!" - Spurgeon. Be careful when you want to share "your version" of the Gospel. Make sure it is THE Gospel of Jesus Christ. Only then will salvation take place.
Our culture isn't the first to be skeptical of the Gospel. The first church faced the same challenge-and God used them to change the world.
