The answer is simple and the truth is profound but there is a great paradox! How can you command emotions that are spontaneous? Is fruit not produced naturally?
Be glad in the LORD and rejoice, you righteous; and shout for joy, all you upright in heart!
Psalm 32:11 (NKJV)
Glad:to brighten...it affects your face
Rejoice...to spin around...it affects your body
Shout for joy...it affects your mouth
All these exhortations are commands! They are commanded in most passages of the Bible; especially the Psalms. In the O.T. righteous people walked with God and lived by faith. God gave the grace to do this. When a person was glad, rejoicing or shouting for joy he was demonstrating that God was His treasure above all else.
Even the New Testament says to rejoice in the Lord. Again I will say rejoicePhilippians 4:11. These are imperatives. So they are the fruit that the Spirit produces in a person that is abiding in Christ, walking with God, walking in the Spirit. If you are not experiencing joy (or any of the other fruits) there is a probable disconnect in your life from walking in the Spirit, Jesus and His Word. Sin definitely wrecks our fellowship and interrupts the Spirit’s flow. But remember the three powerful truths below. Begin to live them out. Ask God to help you.
The secret is to abide in Jesus. To walk in the Spirit. To be filled with the Spirit. If you do the fruit will be produced through the Spirit in you! Look at the Scripture again:
Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unlessyou abide in Me.John 15:4 (NKJV)
I say then: Walkin the Spirit, and you shall not fulfill the lust of the flesh.Galatians 5:16 (NKJV)
And do not be drunk with wine, in which is dissipation; but be filledwith the Spirit, Ephesians 5:18 NKJV)
Fruit is produced naturally. Abiding in Jesus. Walking in the Spirit. And being filled with the Spirit are essential if we are to be fruitful!
