Inasmuch as non-Christians do good, they are working with Christians in doing the will of the Lord Jesus. Non-Christian goodness does not supplant or negate the lordship of Christ. It confirms and demonstrates it.
The relevance of the Church is not dependent on its ability to strategically adjust its message to pertain to what the world is concerned about.

In the aftermath of Harvey, the question we need to be asking ourselves is not, “Why did God punish the people of South Texas and Louisiana?” The question is, “How has God judged me and judged us as a community, as a nation, as human beings?” How has he brought to light things that were lurking deep within your heart? How has he called to you and to all of us to purify ourselves? How has he revealed the light and the darkness within our community and within our nation?
