Goodness is a more difficult Fruit of the Spirit to grasp, at least for me. When I think of good, I think of good grades, a good meal or a good day. It's an adjective of some other noun, but what does goodness mean as an action of faith?
Goodness is the act of being good, choosing right instead of wrong and having moral excellence.
James 1:5 -- "If you need wisdom, ask our generous God, and he will give it to you. He will not rebuke you for asking."
It is easy to get lost in the world, but we can seek God for His guidance. When you do not know right from wrong in any given situation - ask God. He will answer you. Not only will He show you the way, but He will grant mercy on you and remind you of His eternal love.
Isaiah 63:7 -- "I will tell of the Lord’s unfailing love. I will praise the Lord for all he has done. I will rejoice in his great goodness to Israel, which he has granted according to his mercy and love."
1 Peter 2:9 -- "But you are not like that, for you are a chosen people. You are royal priests, a holy nation, God’s very own possession. As a result, you can show others the goodness of God, for he called you out of the darkness into his wonderful light."
Goodness is a long term state of being. You can be good, but it takes being good again and again to exert goodness. It is a definition of your character. Goodness is an outward reflection of your relationship with Christ. Goodness is pouring ourselves and what Christ has given us into others. When we invite Christ to come into our lives and change our heart, our desires, actions and reactions all begin to exert our goodness, our faithfulness in walking with the Lord. It means we not only consciously choose the right, Godly way, but that, over time, it becomes easier to always choose that way.
When we walk in obedience with the Lord, He will fill us and renew us in goodness. Then we can share everything we know about God with others and share His shining light and love with the world.
