Hebrews 4:1 (KJV) 4 Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it.
There are healthy fears, and this is one of them. This is a concluding statement after a warning about hardening of hearts, turning away from God, and failing to enter God’s rest. Praise God; the promise of entering into His rest still stands. However, the possibility of coming short of entering that rest also exists.
God is still so graciously offering His rest to us. How we believers interpret the meaning of coming short of it—failing to enter that rest—may differ, but the seriousness and gravity of the admonition ought to neither be overlooked nor undermined. The blessing offered is very great, it’s just befitting that we take careful and sure steps in our pilgrimage: to have good, right, and godly attitude in all this.
John the Beloved wrote, “There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love” (1 John 4:18); the writer of Hebrews tells us, “Let us therefore fear…” They may seem contradictory, but they are complementary. My humble take: Perfect love casts out fear, except fear of God. We can elaborate and expand on that proposition ad infinitum, but the Scripture is very clear and explicit. To discard one is to err.
