Letter to a Friend Another quality eBook from Chapel Libray. Letter to a Friend is a clear and convincing discussion for the Biblical meaning of “Lordship Salvation.” This controversial doctrine has divided many who otherwise could be partners in the Gospel. Is it a true doctrine found in Scripture or a heresy? If it is truth, is it truth worth fighting over? In his characteristic conversational style, John Piper discusses the logical conclusions he has come to in presenting this important doctrine, one that is vital to understand in order to preach the true Biblical gospel of salvation in Christ alone. The answers come from Scripture, and are appended with all of the relevant texts under topical headings.
