It strengthens us against temptation. The Spirit's goodness helps us love even our enemies. Goodness is also evident in those who live according to the truth of the Gospel, regardless of the necessary sacrifice and suffering. It also inspires us to place our trust in trustworthy persons and to continue to trust in their faithfulness, even though they occasionally fail. The fruit of faithfulness also enable us to believe in our own goodness, even when we sin.
Relationships grow and blossom in an atmosphere of trust.
Just as our trustworthiness provides security and stability to friends and loved ones, so God's faithfulness provides security and stability to us. Our ongoing fidelity to God and others draws us into ever deeper union with God and one another. Furthermore, God entrust the faithful with greater responsibilities and a greater outpouring of divine love. An image which comes to mind when describing gentleness is that of a parent loving a newborn baby. See how the parent tenderly holds the baby.
