Colossians 2 – Part 3: Complete in Him – Rooted and Established in Christ

First Video

Paul has already told the Colossians, “As you therefore have received Christ Jesus the Lord, so walk in Him.” In this final part of the series, he expands that picture: believers are to be rooted and built up in Christ, established in the faith, and abounding in it with thanksgiving. The Christian life certainly involves growth and sanctification, but that growth does not mean gradually making ourselves more acceptable to God through religious effort. We begin in Christ, and we continue in Christ. Our roots are in going deeper into the same gospel, the same Lord, and the same faith we first received. Whatever pressures or difficulties come, the call is to remain established and continue walking faithfully with Him.

That is why verse 8 contains such a strong warning: “Beware lest anyone cheat you through philosophy and empty deceit, according to the tradition of men … and not according to Christ.” The idea is of being taken captive or carried away. False teaching does not always arrive looking obviously false. It can sound impressive, motivational, spiritual or even partly biblical while gradually moving our confidence away from Jesus. Ideas such as “if you only had enough faith you would always be healed”, or “if you give enough, God will guarantee financial abundance”, may sound encouraging, but the question must always be: is this actually what Scripture teaches? Paul’s concern is that believers do not exchange the sufficiency of Christ for human philosophy, religious tradition or what may simply be high-sounding spiritual nonsense.

Paul then gives the reason Christ must remain at the centre: “For in Him dwells all the fullness of the Godhead bodily.” Jesus is not one spiritual being among many, nor a lesser expression of God. John tells us that the Word was God and that the Word became flesh, while 1 John insists upon confessing that Jesus Christ has come in the flesh. Paul’s conclusion follows naturally: “you are complete in Him.” That is not a spiritual level we eventually achieve if we become good enough. It is a reality believers are called to understand and enjoy. We have the Word of God, the indwelling Holy Spirit, prayer, worship and fellowship with God’s people. When we feel as though something is missing, the answer is not to seek a Christianity beyond Christ, but to abide more deeply in the Christ we already have.

Finally, Paul reminds us that Jesus is “the head of all principality and power”. The spiritual realm is not a contest between two equal opposing forces. Christ is supreme. Scripture’s accounts of Job and Peter show that Satan is not autonomous, and 1 Corinthians 10 reminds believers that God remains faithful even in temptation, providing the way to endure. That does not mean the Christian life will be free of attack, temptation or hardship, but it does mean we should never give the enemy greater authority than Scripture gives him. Our confidence rests in Christ – the One in whom all the fullness of God dwells, the One who rules over every power, and the One in whom His people are complete. We do not need something beyond Jesus. We need to know Him more deeply, remain rooted in Him, and live from the assurance of what He has already given us.

Part 3 completes the three-part study through four major truths:

1. Be rooted and established in Christ – Colossians 2:6-7
The Christian life begins in Christ and continues in Christ. Growth means becoming increasingly grounded in the faith rather than seeking some supposedly higher level of spirituality elsewhere.

2. Do not allow human philosophy to take you captive – Colossians 2:8
Teaching should be tested by Scripture. Persuasive words, human tradition, motivational spirituality and attractive promises must never replace the truth found in Christ.

3. All the fullness of God is found in Jesus – Colossians 2:9
Paul directly establishes Christ’s full deity. Jesus is not partly God, a lesser spiritual being or one step within a hierarchy. The fullness of the Godhead dwells bodily in Him.

4. You are complete in Him – Colossians 2:10
Because Christ is fully God and Lord over every principality and power, the believer does not need some additional spiritual secret to become complete. Our life, confidence and spiritual security are found in Him.

The central conclusion of all three parts is therefore:

Christ is not merely enough to begin the Christian life – Christ is enough for the whole Christian life.

How the Three Parts Fit Together

Part 1 – The Great Conflict
Paul agonises in prayer that believers would mature in Christ, remain united in love and grow into full assurance.

Part 2 – Don’t Be Deceived
The mystery is revealed in Christ, and believers are warned against persuasive teaching that adds something beyond Him. The answer is to continue walking and abiding in Christ.

Part 3 – Complete in Him
Paul brings the argument home: remain rooted, reject teaching that takes you captive, recognise the full deity and authority of Jesus, and rest in the truth that you are already complete in Him.

That gives the three-part study a very natural progression:

Pray for maturity → Walk faithfully in Christ → Rest in His complete sufficiency.

Read Colossians 2:6-10 again and pay particular attention to the repeated emphasis upon Christ and in Him. Then ask yourself whether there are teachings, habits or voices that have subtly made your Christian life about something more than Jesus. Return to the simplicity of Paul’s message: receive Him, walk in Him, be rooted in Him and rest in the truth that you are complete in Him.
