The Lord frequently uses comparison and contrast to provide insight for discovering biblical definitions. For instance, our text verse contrasts the carnal with the spiritual. This truth is not limited to our text as 1 Corinthians 3:1 also sets forth this teaching and contrast. In a related study, the Bible repeatedly contrasts the spirit and flesh (Isaiah 31:3; Matthew 26:41; John 3:6; John 6:63; Galatians 5:17). By considering these truths together, we find that the Lord defined a “carnal mind” (Romans 8:7) as someone who is “in the flesh” (Romans 8:8). Based upon these verses and others, we understand the word carnal to mean that which is earthly, natural, or fleshly.
Unfortunately, far too many people today seek to hide the truth behind their lies. This condition is nothing new. In fact, the rulers of Jerusalem claimed to “have made lies our refuge, and under falsehood have we hid ourselves” (Isaiah 28:15). The Lord quickly answered their false assumption. He informed them that their lies would not stand when the Lord passed through their midst with judgment (Isaiah 28:16-19). In verse 20, God offered an illustration of the manner in which their lies would fail to protect them. He said, “the bed is shorter than that a man can stretch himself on it: and the covering narrower than that he can wrap himself in it” (Isaiah 28:20). In other words, no matter how big, well thought out, or cunning a man’s lies may be, they will never be enough. Hiding behind lies is useless and fruitless. Lies can neither support a man nor hide him when the trouble arrives.
