Gal 5:22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness,
Gal 5:23 gentleness, self-control; against such things there is no law.
And conversely, the evidence that one is not being fruitful is:
Gal 5:19 Now the deeds of the flesh are evident, which are: immorality, impurity, sensuality,
Gal 5:20 idolatry, sorcery,enmities, strife, jealousy, outbursts of anger, disputes, dissensions, factions,
Gal 5:21 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.
Jam 3:17 But the wisdom from above is first pure, then peaceable, gentle, reasonable, full of mercy and good fruits, unwavering, without hypocrisy.
Jam 3:18 And the seed whose fruit is righteousness is sown in peace by those who make peace.
Do not confuse these fruits of the spirit with a willingness to compromise belief, or as a sign that one is weak in faith. Indeed it seems to be the exact opposite.
