“And it will come about at that time That I will search Jerusalem with lamps, And I will punish the men Who are stagnant in spirit [that are settled on their lees - KJV], Who say in their hearts, 'The LORD will not do good or evil!'” (Zeph. 1:12)
Pictured here is undisturbed wine. The dregs (lees) have precipitated out, and have not been disturbed for a very long time. When bottles of wine are not rotated in their racks or casks of wine that are not turned, the wine becomes thick and it’s flavor is unchanged. So good wine becomes great and bad wine simply becomes worse. Wicked men, too long undisturbed, sink into sin and degradation that it is impossible to recover from.
Their indifference caused them to think that the Lord cares, rewards or punishes. As the prophet Amos said, they are “at ease in Zion.” (Amos 6:1) It wasn’t they they didn’t know, but that they didn’t care. These are not atheists in profession; yet they are atheists in practice. They don’t take the time or effort to deny God in thought and work out a philosophy of it, they just live like He doesn’t matter, with complete disregard for the Creator who showers them with life and all blessings. So they rest at complete ease in their evil.
Rather than be complacent, and let your sins stack up, continually have the attitude of David: “Search me, O God, and know my heart; Try me and know my anxious thoughts; And see if there be any hurtful way in me, And lead me in the everlasting way.” (Ps. 139:23,24) You know that God will examine everything concerning our lives anyway, so invite Him in to cleanse and perfect it, rather than just waiting until He comes and give punishment for the sin that we’ve all committed.
