I have chosen the way of faithfulness; I set your rules before me. (Psalm 119:30 ESV)
The Fruit of the Spirit is FAITHFULNESS.
Galatians 5:22-23 says, "But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. Against such things, there is no law."
Faithfulness is defined as "steadfast in affection or allegiance." Being faithful does not mean that we understand everything, It means that we trust God is who He says He is, and that He will do what He says He will do. Period. Our part is to be faithful to Him in everything we do and say.
God is faithful to us and we can know that He will fulfill His promises to us.
"God has not called us to success but to faithfulness." – Oswald Chambers
