Maturity: Gal 5:22-25 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law. And those who belong to Christ Jesus have crucified the flesh with its passions and desires. If we live by the Spirit, let us also walk by the Spirit.
The fruit of the Spirit demonstrates maturity, but at the foundation is the crucifixion of our natural selves, the selfish people who we were before being born again (Jn 3:3). The old man (who we were as fallen sinners) was crucified with Christ when the Spirit was planted in us. If we are actually walking in step with the Spirit then we must surely enjoy the benefit of the Holy Spirit displacing our carnal passions and desires.
Completeness: Jn 15:4 Abide in me, and I in you. As the branch cannot bear fruit by itself, unless it abides in the vine, neither can you, unless you abide in me.
We are complete when we are grafted into and remain in the vine of Christ. The sapling doesn’t bear fruit, but the mature plant is complete and does bear fruit. If grafted to the good vine, it bears good fruit.
