God's Gospel is applied by the power of the Holy Spirit.

We believe that salvation, attested in all Scripture and secured by Jesus Christ, is applied to His people by the Holy Spirit. Sent by the Father and the Son, the Holy Spirit glorifies the Lord Jesus Christ and is present with and in believers through the proclamation of the Gospel. He convicts the world of sin, righteousness, and judgment, and by His powerful and mysterious work regenerates spiritually dead sinners, awakening them and persuading to repentance and faith, baptizing them into union with the Lord Jesus, such that they are justified before God. By the Spirit’s working, believers are renewed, sanctified, and adopted into God’s family; they participate in the divine nature and receive His sovereignly distributed gifts. The Holy Spirit is Himself the down payment of the promised inheritance, and in this age indwells, guides, instructs, equips, revives, and empowers believers for Christ-like living and service.
