But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faithfulness….
Some translations have “faith” and others “faithfulness.” The Greek word pistis doesn’t give us much help, since it is translated in a dozen or more ways. Sometimes “faith” refers to a body of doctrine, sometimes to confidence in Jesus, sometimes to the message of Jesus, and so forth.
In the context of the fruit of the Spirit, I’m going with pistis referring to faithfulness, that is, fidelity and loyalty, the quality of being true and steadfast. Reliable.
The Holy Spirit in trust of your life and mine will consistently and increasingly make us true to the Savior, true to the Word, and true to each other.
A phrase every believer serious about his life in Christ would do well to commit to memory is this: A long obedience in the same direction.
The expression originated (as far as can be known) from Friedrich Nietzsche in his book “Beyond Good and Evil:” “The essential thing in heaven and in earth is…that there should be long obedience in the same direction; there thereby results, and has always resulted in the long run, something which has made life worth living.”
That phrase–a long obedience in the same direction–later formed the title of a popular work by Eugene Peterson on Psalms 120-134.
That expression does not sum up what “faithfulness” means to followers of Jesus Christ, but it encompasses three essential parts: 1) obedience, 2) steady, tenured obedience, and 3) in the same direction.
