Hebrews 3:4-6

Hebrews 3:4-6. For every house is builded by some man but he that built all things is God. And Moses verily was faithful in all his house, as a servant, for a testimony of those things which were to be spoken after; but Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.

"But Christ as a Son" - far higher degree -- "Christ as a son over his own house," of which he is the heir, of which he is even now the sole proprietor -- "whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end." None are truly Christ’s but those who persevere in grace. Men may be nominally Christ’s, but they are not Christ’s house unless they hold fast to the confidence and the rejoicing of the hope firm unto the end. Temporary Christians are not really Christians.
