We need to keep the focus on Christ as Christians. The gospel of the forgiveness of sins for all who come to Jesus is the center of Christianity.
Too often we and the church get caught up on small matters. The matters seem important or may be important but the gospel gets pushed to the side.
The gospel can never be pushed to the side in the church. Often the church wants to improve the behavior of its members by ethical teaching.
And while ethics and teaching on Christian living are of great use, the ethics and Christian living are always rooted in the cross. If we focus too much on ethics and forget the root of ethics we loose the power of the gospel.
The gospel has the power to change the world. That is why the gospel must always be kept at the center of the church.
If you want to save souls you need to the gospel. If you need to have people become better they need the gospel. If you need people who profess to be Christians, but live poorly, you need to get them to really understand the gospel.
The gospel is the power with which the world is overcome. The world will not be improved much by ethics, but it will be improved by truly grasping the glory of the risen Jesus. Let us keep our eyes on the author and perfecter of our faith.
