Two pursuits, yet very similar.
Jerry Bridges wrote two books, "The Pursuit of Holiness" and "The Practice of Godliness".
Holiness and Godliness are two callings of a Christian; similar, but Bridges makes a distinction. In the book on holiness, he talks about putting off the old man, Godliness is about putting on the new man.
Neither one of these works unless you include a generous sprinking of the Gospel. Unless we have a full understanding that we are called to be perfect, but the only perfection we can rely on is the perfection of Christ, we will run into deep anger and dispair at the failure of our efforts. If we don't understand that we cannot to it on our own, we run into deep pride.
And still, we are called to holiness, Godliness; we are called to be perfect, for the Lord our God is perfect.
What does it mean to be "holy"? We turn away from that which is sin. We love what is good and we hate what is evil.
What makes God angry also makes us angry.
In the call to holiness and Godliness, we strive (with the Spirit's sanctification) to become more like Christ.
What made Christ angry? Those religious people who took what was evil and called it "good".
Immediately, Gene Robinson comes to mind. Those religous people who look at abortion and call it a good, human right.
Those who look at women and call them inferior, denying them an education and a voice. Men who abuse their wives and call it "leadership".
You see, there are extremes on either side. To examine the extreme on one side without examining the log on your own side...
