Our words should never be used by the Devil as weapons to destroy or discourage others. Any problem with our words reveals a problem with our heart: “out of the abundance of the heart the mouth speaketh” (Matthew 12:34). The mouth can exhibit good or bad and our actions reveal the heart of the problem when the Bible says, “out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies” (Matthew 15:19). This is why our words are not always profitable to those who hear them. Yet, God admonishes us to “let no corrupt communication proceed out of” our mouth. Believers are instead encouraged to make sure their words are “good to the use of edifying.” The saint of God should speak words that God can use to build up other saints in the faith.
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.
