The sermon teaches that because Christians have died and been raised with Christ, they must not return to the slavery of human regulations and counterfeit spirituality from which Christ has freed them. False religion may have an appearance of wisdom through rules, asceticism, religious experiences, and outward displays of holiness, but these are merely imitations that cannot justify sinners or produce true sanctification. Paul therefore asks why those who have died to the world would again submit to commands such as "do not handle, do not taste, do not touch," especially when these originate in human teachings rather than Christ. True spiritual growth does not come through self-made religion or external regulations, but by holding fast to Christ, the Head of the Church, from whom God produces genuine growth. The sermon emphasizes that Christ has reconciled His people, canceled their debt, disarmed their enemies, and given them new life; therefore, believers obey not to earn salvation but because they have already been made alive in Him. Christians must discern counterfeit religion by Scripture and the gospel, refusing anything that places human works alongside Christ's finished work. Ultimately, the question is whether Christ Himself is sufficient, because only union with Him produces genuine freedom, holiness, and life rather than a mere imitation of spirituality.
