Unmistakably there exists a wide gulf of separation between the children of God and the children of the world. Christ is the only avenue of escape from the world. The wide, open door of salvation is the exit. He who would return from the blissful shores of Christianity to the beggarly elements of the world can do so only on the transporting barges of Satan. As a tree is known by its fruits, so is a true follower of Christ. The fruit borne by a Christian is directly opposite in its nature to the fruit borne by the worldling. It is not the profession merely that produces the separation, but it is the manner of life. The Son of God is the great exemplar of Christianity. Just what true Christian principles did in him will in the very nature of things do for all who possess like principles. We are forced to the conclusion that the professed follower of Christ is destitute of Christian principles when he delights himself in worldliness. Jesus said of himself, “I am not of this world.” John 8:23. He says of his followers, “If ye were of the world, the world would love his own: but because ye are not of the world, but I have chosen you out of the world, therefore the world hateth you.” John 15:19. Paul bears testimony to his separation from the world by the grace of God. In Eph. 2:2, 3 he speaks of the time when he lived among those who were worldly. He says, “Wherein [in sin] in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience: among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind: and were by nature the children of wrath, even as others.” In the next two verses he testifies to the effects of saving grace: “But God, who is rich in mercy, for his great love wherewith he loved us, even when we were dead in sins, hath quickened us together with Christ; by grace ye are saved.” It must be made obvious to all by these texts that salvation from sin by grace saves from walking according to the course of the world.
