5 …Of this you have heard before in the word of truth, the gospel, 6 which has come to you, as indeed in the whole world it is bearing fruit and growing—as it also does among you, since the day you heard it and understood the grace of God in truth.
9 And so, from the day we heard, we have not ceased to pray for you, asking that you may be filled with the knowledge of his will in all spiritual wisdom and understanding, 10 so as to walk in a manner worthy of the Lord, fully pleasing to him, bearing fruit in every good work and increasing in the knowledge of God.
The phrases “bearing fruit and growing” in v. 6 and “bearing fruit…and increasing” in v. 10 are actually the same words in Greek. The gospel, by its very nature, produces results on both a worldwide and an individual level.
The analogy here is that the gospel is like a tree. It grows as the worldwide church increases in number and as each Christian increases in the knowledge of God. It bears fruit as each believer devotes himself to doing good works for the glory of God, and as the church is united in doing good for the sake of Jesus Christ.
The gospel is a seed that, when planted in a fertile heart, grows into something great. May God soften our hearts and cause us to grow in knowledge and bear fruit for His kingdom.
