The opportunity for the flesh of which Paul writes is primarily our tendency to “bite and devour one another” and the inevitable consequence of being “consumed by one another.” (Galatains 5: 15) Indulging the sinful nature is the opposite of love, says Paul. “For the entire law is fulfilled in one statement: ‘Love your neighbor as yourself.’ ” (Galatians 5: 14)
Bitter argument and rivalry are not of the Holy Spirit, but of the sinful nature — the flesh. “Since we [who are in Christ] live by the Spirit, we must also follow the Spirit. We must not become conceited, provoking one another, envying one another.” (Galatians 5: 25 – 26)
Instead, love one another. “Love is patient, love is kind. Love does not envy, is boastful, is not conceited, does not act improperly, is not selfish, is not provoked, and does not keep a record of wrongs. Love finds no joy in unrighteousness but rejoices in the truth. It bears all things, believes all things, hopes all things, endures all things. Love never ends.” (1 Corinthians 13: 4 – 8)
Therefore, Paul reminds us not to use our freedom in Christ as an excuse to consume one another in jealousy, envy, rivalry, and conceit. Let us rejoice in our freedom, loving one another as Christ first loves us.
