He wist not that the Lord was departed from him - Judges 16:20
Beware of unconscious deterioration! Grey hairs may be here and there upon us without our knowing it. The Lord may be gone out on feet so noiseless, that we are not aware that His Spirit has glided along the corridor, and through the doorway, whispering, Let us depart.
Deterioration is unconscious because it is so gradual. The rot that sets in on autumn fruit is very gradual. The damp that silences the violin or piano does its work almost imperceptibly. Satan is too knowing to plunge us into some outrageous sin at a bound. He has sappers and miners engaged long before the explosion, in hollowing subterranean passages through the soul, and filling them with explosives.
Spiritual declension blunts our sensibility. The first act of the burglar is to gag the voice that might alarm, and poison the watch-dog. So, sin blinds our eyes, and dulls our keen alertness to the presence of evil. Thus, the stages of our relapse are obvious to all eyes but our own. We are drugged as we are being carried off captives.
The progress of evil within us is a matter of unconsciousness, largely because we are quick to discover reasons to justify our decadence. We gloze over the real state of affairs. We call sins by other names. We insist on considerations which in our eyes appear to justify our conduct. We still attend to our religious duties, and try to persuade ourselves that it is with us as in times past. To avoid deterioration we must ever watch and pray, and realize that we are the temple of the Holy Ghost. Then shall the peace of God as a sentry guard our hearts and our thoughts in Christ Jesus.
