The Gospel continues to save by sustaining believers through faith, working in them as they hear and trust in Christ.
The Gospel of Jesus Christ is not a one-time event but an ongoing source of salvation for believers. As noted in Ephesians 1:13, upon trusting in the Gospel, believers are sealed with the Holy Spirit, which is the earnest of their inheritance until redemption. This indicates that salvation is both an initial act and a continuing process that involves growth and preservation of faith. The preaching of the Gospel serves to remind believers of their dependence on Christ and reinforces their assurance through the gifts of the Spirit. It is by regularly engaging with the Gospel that Christians find themselves strengthened and upheld in their walk of faith.
