They do not live upon CHRIST

"I beseech you, as you value your privileges, and high calling in CHRIST; learn of GOD the SPIRIT how to estimate your safety in CHRIST. So wretchedly low at present is the tide of things, in the spiritual life of GOD in the soul, according to modern profession, of what some men call the Gospel; that in this land, where once it stood at high water mark, it is now nearly gone out, and left our shore at the lowest ebb. They do not live upon CHRIST, but upon their own self attainments. And while any thing in self, can be found to satisfy their minds, they are at ease; though they have no communication, from the ocean of CHRIST, in those streams, which alone can truly make glad the city of GOD, Psalm 46:4." -Robert Hawker, Commentary on Hebrews 3
