I will yet add, There is a love of Christ, I will not say, that cannot be known, but I will say, that cannot be enjoyed; no, not by them now in heaven (in soul) until the day of judgment. And the knowledge of this, when it has possessed even men on earth, has made them choose a day of judgment, before a day of death, that they might know what is beyond that state and knowledge which even the spirits of just men made perfect, now do enjoy in heaven (2 Cor 5:4). Wherefore, as I said at first, To know the love of Christ that passeth knowledge, is advantageous upon this account; it begetteth in Christians a great desire to reach, and press forward to that which is before.
One thing more, and then, as to this reason, I have done. Even that love of Christ that is absolutely unknowable, as to the utmost bound thereof because it is eternal, will be yet in the nature of it sweet and desirable, because we shall enjoy or be possessed of it so. This therefore, if there were no more, is enough, when known, to draw away the heart from things that are below, to itself.
(4.) The love that passeth knowledge. The knowledge of that is a very fruitful knowledge. It cannot be, but it must be fruitful. Some knowledge is empty, and alone, not attended with that good, and with those blessings wherewith this knowledge is attended. Did I say, it is fruitful? I will add, it is attended with the best fruit; it yieldeth the best wine: It fills the soul with all the fullness of God. "And to know the love of Christ which passeth knowledge, that ye may be filled with all the fullness of God." God is in Christ, and makes himself known to us by the love of Christ. "Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God," for God is not to be found nor enjoyed, but in him, consequently, he that hath, and abideth in the doctrine of Christ, "hath both the Father and the Son" (2 John 9). Now, since there are degrees of knowledge of this doctrine, and since the highest degree of the knowledge of him, is to know that he has a Love that passeth knowledge, it follows, that if he that has the least saving knowledge of this doctrine, hath God; he that hath the largest knowledge of it, has God much more, or, according to the text, is filled with all the fullness of God. What this fullness of God should be, is best gathered from such sayings of the Holy Ghost, as come nearest to this, in language, filled,
Full of goodness (Rom 15:14).
Full of faith (Acts 6:5).
Full of the Holy Ghost (Acts 7:55).
Full of assurance of faith (Heb 10:22).
Full of assurance of hope (Heb 6:11).
Full of joy unspeakable, and full of glory (1 Peter 1:8).
Full of joy (1 John 1:4).
