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.
Fruit thrives within the right environment with the proper living conditions. The same holds true concerning God's virtues in the life of a Christian. It is God's indwelling Spirit that provides the fertile environment necessary for every believer to cultivate these virtues. They include love, joy, peace, and faith. Only as Christians submit to the leading of the Holy Ghost can we fully access these virtues. Though mentioned last in the list from Galatians, temperance is another of the important virtues making up the fruit of the Spirit. Though frequently neglected, temperance is no less important than the other virtues naturally growing in the life of a fertile believer. A disregard for the proper mix in the Christian life causes imbalance. Believers who fail to cultivate stability and peace by not yielding control to God's indwelling Spirit never realize their God-given potential.
