Men try to get a new heart not by trying to turn from all sin, but by praying for it. I meet such a man. I prayed for a new heart. Therefore, all your doings come short of what God requires. They fail of saving the soul from sin.

And here let me give you a case. Being out from home in my carriage, I overtook a young man and invited him to ride. Almost immediately he told me he was a Universalist and came out strongly in defence of his system. He said for his part he was sure enough of its truth. He had heard smart men say so, and prove it from Scripture.
