“Go in through the narrow gate, because the gate to hell is wide and the road that leads to it is easy, and there are many who travel it. But the gate to life is narrow and the way that leads to it is hard, and there are few people who find it.” (Mattherw 7:13-14 TEV)
If, day by day, I stay on the narrow road, I have God’s promise that I will arrive at my destination. But if I choose to leave the narrow road that leads to salvation and get on the wide road that leads to destruction, won’t I arrive at the same destination as the ones who were never on the narrow road to begin with?
Jesus’ promise to those believers who face persecution in the last days is good for the rest as well: “The one who endures to the end … will be saved.” (Mark 13:13b NLT) I don’t find Jesus saying that believers who don’t endure to the end will be saved anyway.
That’s because a believer who quits enduring isn’t a believer any more. Security is for believers.
