The best passage would be this...
Gal. 5:22-23 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law.
Man can fake love, joy, peace, meeknes.....but those are merely plastic fruits that have no life in them. Those are performed through man's own efforts. We see that all the time...of the flesh.
The genuine article (meekness, love, etc.) is the Spirit's, not ours or performed by us. The Spirit performs His work in and through us.
2 Corinthians 12:9 And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me.
