The Gospel is the Grace of God, and the Grace of God is the Gospel!  If it's not the Grace of God, then it is not the pure Gospel.  A few of the genuine proofs of True Grace are an awakening unto the Indwelling "Christ-in-us", and a sincere desire to gather, fellowship and serve one another... as brethren... by love.  Yes, Grace is the Expression of the Love of the Father.  Grace is not self-seeking or self-serving, but proceeds from unfeigned love.  Toward the end of The Parable of the Two Prodigal Sons, we see our Father's desire is not to divide and separate us from one another, so that we can "hold on" and wait for a "rapture" to save us from some "anti-Christ"; but to have His love perfected in us toward one another, to have His Sons gather, fellowship and love on one another... as they feast on the Fatted Ox, the real-deal Five-Fold Ministry that further roots and ground His Sons in our Heavenly Identity.  In regard to the Seven Churches in The Book of the Revelation of Jesus Christ, it is revealed that the Seven Churches have fallen from Grace; and are now dividing themselves, alienating themselves, from one another, much like the Older Prodigal's not wanting to enter into his own Father's "house" (a corporate gathering together) because of the presence of his own, Younger Prodigal-Brother).  The Seven Churches divide and separate themselves based on four (#4 is associated with the Old Creature or Creation) things: 1. "nations," or ethnicity (ethnic pride); 2.  "kindreds," or worshiping and following after the "familiar" or "family" spirits associated with "belonging" unto the names of famous preachers whom we substitute for personal fellowship with both the Father and one another; 3. "tongues," or doctrines we worship and idolize, which have nothing to do with the Doctrine of God, "Christ in You, the Hope of Glory"; 4. "peoples," or social groups that gather around anything other than the things of God, or which pertain unto the revelation of Christ.
