Joy

Galatians 5: 22-23
By contrast, the fruit of the Spirit is love, joy, peace, patience, kindness, generosity, faithfulness, gentleness, and self-control. There is no law against such things.

Plain and simple: Joy is a fruit. . . it must be grown.

So let me help you understand. Joy, like all the other fruit, is grown from a small seed which is the Word of God (Mark 4: 14). It must be planted in the soil of your heart (Luke 8: 15) and then watered from heaven either by a direct downpour or some gentle teaching (Deuteronomy 32: 2) so that the roots go down deep. Then, at the appointed time, a tree will spring forth and grow. Wow! a miracle because it issues forth from God's design and exists only because of his "doing" (1 Corinthians 3: 7). He gives it life by placing his Spirit within (2 Corinthians 3: 6). Do you see? It is fruit of the Spirit. The fruit comes from Him (that is, God the Holy Spirit), and by no other means. And when the sun shines down on us because Jesus Christ, the Son of the Living God, and his Righteousness is lifted high like the noonday sun in our lives, our fruit begins to ripen.

So 'Yes' there is a purpose because his fruit is meant for sharing. . . . so that others may taste and see that the Lord is good! . . . and more seeds may be planted.

Aha! I'm back to Evangelism and nothing less.

Psalm 1: 1 - 3
Happy are those who do not follow the advice of the wicked, or take the path that sinners tread, or sit in the seat of scoffers; but their delight is in the law of the Lord, and on his law they meditate day and night. They are like trees planted by streams of water, which yield their fruit in its season, and their leaves do not wither. In all that they do, they prosper.
