If a man's heart is reborn his life will be reborn. And if one man's life is reborn, that productive, God-glorifying life will positively effect the society in which he lives.
The very concept of Christianity asserts that physical and mental well-being come from a correct world view which is God-centered. When our perspective changes, our lives change and thus, society is impacted positively.
All as God wills.
Or else you've declared defeat before the game is over.
“You keep confusing the liberal “social gospel” (change society and you will change the man)”
No, there is no confusion. We were talking about how the systems change with the changes in circumstance, like dates, progress, “eccentrics” etc. What I was pointing out is that over time as circumstances changed even the post-mil optimism changed from a confident “Rise Up Oh Men of God” to a quiet movement like yeast. The liberal social gospel arose out of the preaching of post-mil scholars because of their confidence that this was the millennium and the church was ushering in the kingdom and man was getting better so the church should eradicate cultural deficiencies with its programs. Those darn wars came at such an inconvenient time.
