As many as I love, I rebuke and chasten: be zealous therefore, and repent. As many as. Not one whom God loves escapes chastening; if he be not chastened, he is not a son (Hebrews 12:8), for "all have sinned, and come short."
"I love" is φιλῶ, I love dearly; not merely ἀγαπῶ. I rebuke ( ἐλέγχω), to reprove, so as to convict of sin and turn to repentance; the work of the Holy Ghost, who should "convict the world of sin" (John 16:8).
This verse is a solace and encouragement for the Laodi-ceans. They were required to make the sacrifices demanded of them, not so much that they might be punished for their transgressions, but to prove themselves of the number of God's elect.
The stern reproof administered was a pruning, which was an evidence of God's loving care for them; the final sentence, "Cut it down," had not yet gone forth. But though thus intended for encouragement rather than condemnation, yet it could not but contain implied reproach, however tender.
No one can be exhorted to change his path and to seek that which is holy without being reminded that he is unholy and has wandered from the right way. Those in Laodicea who took this message to heart must needs think of their unchastened life—the life full of prosperity and self-satisfied security, into which so little zeal had been infused, in which so little need for repentance bad been felt.
The Church, indeed, needed some of that chastening, that persecution, and hardship, which should arouse her from the perilous slumber of ease into which she had fallen, and call forth some zeal and self-sacrifice, the frequent and natural result of opposition.
