How do we know that faith is important for saving?

Faith is the means by which we come to God, as stated in Hebrews 11:6, which tells us that without faith, it is impossible to please God. This faith is an acknowledgment of Christ's sufficiency—He is all we need for salvation and righteousness. In the illustration of the widow's two mites, her act of giving represents a profound trust in God's provision; she gave all she had, showing that her faith was in God alone. The true measure of faith rests not on our works or intentions, but solely on Christ's completed work on our behalf, emphasizing that we must come to Christ as our only hope for salvation.
