How do we know that God's grace is free?

The concept of God's grace being free is rooted deeply in scriptural teaching, particularly as found in Ephesians 2:8-9, which states that we are saved by grace through faith, and that not of ourselves; it is the gift of God. This means it is not based on works, highlighting that salvation cannot be earned through human effort or morality but is given freely by God to those who believe. The analogy made in the sermon, comparing receiving grace to accepting a gift that you cannot afford, further clarifies that God's grace is beyond any transaction of worth and is offered solely out of His lovingkindness.
