Galatians 5: 19-23
"Now the deeds of the flesh are evident, which are: immorality, impurity, sensuality, idolatry, sorcery, enmities, strife, jealousy, outbursts of anger, disputes, dissensions, factions, envying, drunkenness, carousing, and things like these, of which I forewarn you, just as I have forewarned you, that those who practice such things will not inherit the kingdom of God.
But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law."

 

Contrast of Flesh and Spirit
The deeds of the Corinthians matched very well with the deeds of the flesh. To counter this, Paul sent Timothy to Corinth as a living example of fruit of the Spirit.

The message to the Galatians was that the life of God's kingdom was one of the Spirit and that this life will be evidenced by fruits of the Spirit. Those stuck in the deeds of the flesh of the old covenant were outside of God's kingdom.
