There are only two of these seven churches that receive no reproof, and Philadelphia is the second. Philadelphia used to be known in those days as the gateway to the East.
Those people who today want to win souls with rock bands and choirs and drama and very little preaching, and even by softening down any reference to sin and Calvary and salvation are in effect addressed by Christ here. I am the one, he says, who opens the door of opportunity and the door of the kingdom of God, and if I open it nothing can prevent it, not all the atheism in the world, nor all the derision and the scorn of men. I will take people out of the middle of even that and remove their prejudice and their pride, and as they hear my word I will save them by the power of my Spirit. We do not need all these things. They are not only worldly gimmicks, worldly methods, offensive to God, but we do not need them. So away with them all, let us go back everywhere to reverent worship, putting the word in centre place, relying by prayer on the Spirit of God. And we have this tremendous comfort and assurance which Christ gives to Philadelphia.
