Everything good flows down from above, from God, as per Jas. 1:17. God works through His truly called and ordained pastors and elders, who then bring the gospel to Christ’s church. The parishioners then begin to conceive of themselves as the Lord’s gospel “foot soldiers,” His agents on earth. The believing church is God’s salt and light in the world.
Culture begins to be changed, and is transformed automatically, simply from the doing of the right thing. But the place where “the right thing” must begin is the worship service in church, on Sunday. Once the believers learn to think “covenantally,” or in a church-centered way, everything else begins to take on new (redemptive) shape as well.
The great error of our day, (and it has actually been around since the Fall itself), is to imagine that somehow God has altered His course, and that He will operate aside from His biblical system (of Sunday, church, and worship). But the truth of the matter is that the Lord has never abandoned this grand program. Through it He will win the world—but not in any other way.
