How does God establish believers according to the Gospel?

In Romans 16:25, Paul declares that God is 'of power to establish you according to my gospel.' This affirmation underscores the vital role that the Gospel plays in grounding believers in their faith. The establishment of believers occurs through the work of the Holy Spirit who applies the truth of God's Word to the hearts of those who hear. This divine establishment isn't about mere intellectual acceptance; rather, it involves a transformational experience of the soul, moving from death to life, by the power of Christ's resurrection. Every Christian's foundation is built on this Gospel, which gives them the confidence and assurance needed to stand firm in their faith amid trials.
