To him that overcometh will I give to eat of the tree of life, which is in the midst of the paradise of God. -Revelation 2:7
No man may turn his back in the day of battle or refuse to go to the holy war. We must fight if we would reign, and we must carry on the warfare till we overcome every enemy, or else this promise is not for us, since it is only for “him that overcometh.” We are to overcome the false prophets who have come into the world and all the evils which accompany their teaching. We are to overcome our own faintness of heart and tendency to decline from our first love. Read the whole of the Spirit’s word to the church at Ephesus.
If by grace we win the day, as we shall if we truly follow our conquering Leader, then we shall be admitted to the very center of the paradise of God and shall be permitted to pass by the cherub and his flaming sword and come to that guarded tree, whereof if a man eat, he shall live forever. We shall thus escape that endless death which is the doom of sin and gain that everlasting life which is the seal of innocence, the outgrowth of immortal principles of Godlike holiness. Come, my heart, pluck up courage! To flee the conflict will be to lose the joys of the new and better Eden; to fight unto victory is to walk with God in paradise.
