Two things can never be present for a church to be healthy. Paul says, "Do nothing out of selfish ambition or conceit."
In a practical sense, he says we are not allowed to strive for personal achievement in the church. It can never be about our own advancement. Seeking the good of others must be at the forefront of our minds. We are also called to set aside thoughts that we are better than others. Ambition and conceit have no place in God's house.
We are to think like Jesus.
He was humble and took the role of a servant. If we want to know how genuine our faith is, all we must do is examine how we treat others.
The beauty of Christianity is that it works when we live it out as intended. It solves our greatest spiritual need and leads to a life of joy with others. The Gospel is true, and our lives should be lived like it is true.
