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.
On the surface, one might superficially define peace as an absence of war, troubles, or trials. Yet, the Bible indicates a much broader concept. Two words in our passage suggest as much. The Bible says, “the work of righteousness shall be peace; and the effect of righteousness quietness and assurance for ever.” The next verse states that God’s “people shall dwell in a peaceable habitation, and in sure dwellings, and in quiet resting places.” Both verses incorporate the words quietness and assurance revealing that peace offers a quiet assurance. Fortunately, this means that peace for the child of God is not contingent upon the circumstances of life. Christians can experience peace even while enduring the worst of circumstances.
