While all believers benefit from God’s grace, Paul sounded a warning about how we should all live:
Galatians 6:7-8 Don’t be misled—you cannot mock the justice of God. You will always harvest what you plant. Those who live only to satisfy their own sinful nature will harvest decay and death from that sinful nature. But those who live to please the Spirit will harvest everlasting life from the Spirit.
So how can you know someone is living to please God?
Galatians 5:22-23 But the Holy Spirit produces this kind of fruit in our lives: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. There is no law against these things!
And to go one step further,
Galatians 5:24 Those who belong to Christ Jesus have nailed the passions and desires of their sinful nature to his cross and crucified them there.
In contrast, not living by the Spirit results in decay and death:
Galatians 5:19-21 When you follow the desires of your sinful nature, the results are very clear: sexual immorality, impurity, lustful pleasures, idolatry, sorcery, hostility, quarreling, jealousy, outbursts of anger, selfish ambition, dissension, division, envy, drunkenness, wild parties, and other sins like these. Let me tell you again, as I have before, that anyone living that sort of life will not inherit the Kingdom of God.
