How do we know that God's grace brings salvation?

The assurance of salvation through God’s grace rests in the finished work of Christ on the cross. As stated in the sermon, the gospel of grace is the good news that God does not require us to fulfill the law for salvation; instead, Christ has perfectly completed this task on our behalf. His statement, 'It is finished,' signifies that all the demands of justice have been met. Furthermore, Scripture affirms that salvation is solely a gift received by faith, emphasizing that it is not of ourselves but is the work of God. Therefore, God's grace is both the source and means through which we receive eternal life, reminding believers that our salvation is entirely reliant upon His mercy.
