9And 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, 10so 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 heart of Christian unity is found in the prayers of the saints. It is a unique character trait of the believer that permits such a response to the report of love in the Spirit. There is no desire for them to excel in fame or prestige. There is no passing apathy resulting from a competitive spirit. There is no desire to direct their steps and take charge of them. On the contrary, Paul prays for them to know God’s will and understand it.
What a tremendous prayer! That the Colossians would “be filled with the knowledge of His will” (v.9). He does not merely pray for some knowledge or a provision of knowledge. Rather, Paul prays that they would be filled with knowledge. Further, it is not simply general knowledge that Paul seeks, but especially the knowledge of God’s will. The will of God: that sovereign desire that will be brought to fruition. Paul prays that they would be complete in their knowledge of God’s will. Imagine what it must mean to be complete in the knowledge of God’s will. Such knowledge would bring tremendous confidence. That very confidence that is needed to face trial and the strength to overcome sin are wrapped in the knowledge of God’s sovereign will. Take note, it is not knowledge of the specifics of God’s plan or His direct intention. Rather, it is a knowledge of His will specifically. Christians do not require knowledge of every detail of God’s plan, only the full knowledge that He has such a will and can be trusted. As the Christian becomes more aware of and confident in God’s will, the strength of their walk grows.
The knowledge of God’s will is accompanied and processed by “spiritual wisdom and understanding” (v9). This is faith that is complete. Complete faith does not merely trust in the knowledge that God’s will is sovereign, it also understands it and responds to it in wisdom. Christians who trust in God ought to live as the wisest among mankind. The wisdom of Christians ought to exceed the wisdom of the world, precisely because the nature of Christian wisdom is spiritual. The wisdom of Christians extends beyond the temporal world and exists in spiritual realms. As a result, the wisdom of Christians comes from a source that both influences and alters both temporal and spiritual realities.
Paul’s desire for the Colossians is that their lives would reflect the holiness of God. Christians live differently from the world around them. They live a life that is set apart. A life that is in pursuit of holiness. So, Paul prays that they would have the knowledge to enable such Christ-like living. Knowledge is given to Christians for the purpose of a changed life. A person who claims to know Christ and yet remains unchanged and unholy does not know the Lord. An unchanged Christian is not a Christian at all.
The life that is worthy is here explained in three descriptions each beginning with a participial phrase. The first description bears itself out in three simple phrases of verse ten. First, it is a life that is pleasing to God. That is to say, it is a life that delights in the word of the Lord and pursues holiness. It is not merely a passing delight. The life that is worthy is one that is “fully pleasing!” It is a life that delights God in every aspect. The Christian life is one that brings joy to the Lord not only in the view of the public but also in the secluded moments of privacy. Second, it is a life that bears fruit that is displayed in the work of the Christian life. The fruit of a Christian is not measured in tangible numbers or acts of people. Rather, the fruit of the Spirit is evident in the character of the Christian (C.f. Galatians 5). Yet, the fruit of the Christian life is born out in the works that Christians do to love their neighbors. It is revealed in “every good work.” Note that it is every work, not merely the ones that have been performed for an audience or in view of specific groups. The fruit of a Christian is displayed in all the works that are accomplished both public and private. Further, Christ admonishes His disciples in John 14 that the world will know His disciples by the way they love. Christians who bear fruit, work. Finally, the worthy life is one that increases in the knowledge of God. A Christian who does not grow in their knowledge of God is either starving their soul or they have not been redeemed. Either way, they are missing the delight and power of the Christian life. The worthy life is one that is spent tenaciously pursuing God. The worthy life is one that lays its selfish desires aside for the sake of knowing the Creator of the universe. The worthy life is a life surrendered to the pursuit of God.
The life of a believer is a changed life. It is a life that both defies the calls to success from the material world around it and embraces a tenacious love for that world. The Christian life is a life altered by the creator of all things. It is a life that is radical in its love towards others, relentless in its pursuit of holiness, and constant in its praise of God.
Oh Christian, how beautiful a worthy life is! Consider what our world would look like if believers genuinely pursued Christ so as to live a worthy life. Such great love would be displayed that the whole world would be forced to take notice. Indeed true Christianity has this effect on the community that surrounds it. When believers work to live lives worthy of the Gospel of Jesus Christ, the world around them is made more beautiful by the outflow of love that results from their pursuit of God. Pray, dear Christian that you and the other brothers in the faith would be filled with the knowledge of God. In that knowledge, the world will see the glory of God!
