What role does spiritual life play in salvation?

Spiritual life is central to the concept of salvation in Reformed theology. It is not a product of human effort but a miraculous work of God through the Holy Spirit. When a person is saved, they are granted new spiritual life, which leads to a transformation in their daily existence and relationship with God. This life is evidence of God’s promise being fulfilled, affirming that we are indeed His people. Thus, spiritual life manifests itself in faith, obedience, and a growing desire to know Christ more deeply and live according to His will.
