"A highway shall be there, and a road, and it shall be called the Highway of Holiness. The unclean shall not pass over it, but it shall be for others. Whoever walks the road, although a fool, shall not go astray. No lion shall be there, nor shall any ravenous beast go up on it; it shall not be found there. But the redeemed shall walk there, and the ransomed of the LORD shall return, and come to Zion with singing, with everlasting joy on their heads. They shall obtain joy and gladness, and sorrow and sighing shall flee away. Enter by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and there are many who go in by it. Because narrow is the gate and difficult is the way which leads to life, and there are few who find it.

Then one said to Him, “Lord, are there few who are saved?” And He said to them, “Strive to enter through the narrow gate, for many, I say to you, will seek to enter and will not be able. He who overcomes shall be clothed in white garments, and I will not blot out his name from the Book of Life; but I will confess his name before My Father and before His angels." For whatever is born of God overcomes the world. And this is the victory that has overcome the world — our faith. Who is he who overcomes the world, but he who believes that Jesus is the Son of God?"
