You, my brothers, were called to be free. But do not use your freedom to indulge the sinful nature; rather, serve one another in love.
It is said “to whom much is given, much is also expected.” This is essentially what Paul tells the Galatians. Christians have been given grace and are free from the consequences of sin – inasmuch as it affects our salvation at least.
We should use that freedom wisely. This means that we shouldn’t use forgiveness as an excuse to sin. Just because we know that God will forgive us does not make it acceptable for us to engage in sinful activities.
God’s love and grace extend beyond any sin that we can commit. But Christians should still strive to avoid sin because we love the Lord and because it affects our life. There are physical consequences to sin as well as spiritual ones that harm our relationship with God.
Instead of living a sinful life, Christians should strive for righteousness and to live according to God’s law. Instead of sinning, we should seek to serve one another.
