How does one have faithfulness? Well, it all starts when you accept Christ Jesus as your Savior and are given the gift of the Holy Spirit to dwell within you. From there, if you choose to turn away from your sinful nature and live by the Spirit, you will then have the fruit of the Spirit. This fruit consists of love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness, and self-control.
