Religion or Christianity?
A Sermon on John 5:31-35
If I alone bear witness about myself, my testimony is not true. There is another who bears witness about me, and I know that the testimony that he bears about me is true. You sent to John, and he has borne witness to the truth. Not that the testimony that I receive is from man, but I say these things so that you may be saved. He was a burning and shining lamp, and you were willing to rejoice for a while in his light. (ESV)
The general appeal of religion; and its dangers; temporary believers; false ideas of Christianity.
