How do we know salvation is solely by God's grace?

The sermon emphasizes that salvation is entirely a work of God's grace, rooted in His character as a merciful and compassionate God. Isaiah 48:10 says, 'I have refined thee, but not with silver; I have chosen thee in the furnace of affliction.' This verse illustrates that God's choosing and saving work is not based on our worthiness or actions but stems from His sovereign will and purpose. It’s reminded that faith itself is a gift from God, not an accomplishment of man, thus reinforcing that salvation belongs to the Lord alone. As believers, we can take comfort in knowing our salvation is secure, as it relies on Christ's finished work rather than our fluctuating efforts.
