THE DOCTRINE OF CHRIST” VS “THE GOSPEL OF CHRIST
“The Doctrine of Christ” is the “heart and soul” of Christianity, it tells us the “what and why” of what we must do for us to have Eternal Life.
“The Gospel of Christ” is the heart and soul of the how we are to teach the Word of God to an unsaved world (concerning Salvation).
BOTH share the same teachings and message but are different in their presentation and purpose.
