18 Therefore, my brethren, let no man deceive you, let no man seduce you: love the peace of Christ, who was crucified for you, while He was God. Paul says, “Neither he that plants is anything, neither he that waters, but God who gives the increase.” And does any of us say that he is something? If we say that we are something, and give not the glory to Him, we are adulterers; we desire ourselves to be loved, not the Bridegroom. Love ye Christ, and us in Him, in whom also you are beloved by us. Let the members love one another, but live all under the Head. With grief indeed, my brethren, I have been obliged to speak much, and yet I have said little: I have not been able to finish the passage; God will help us to finish it in due season. I did not wish to burden your hearts further; I wish them to be free for sighs and prayers in behalf of those who are still deaf and do not understand.
