We know God's grace is free because it is given without any conditions imposed on us, as exemplified in the gospel message.
The concept of free grace is established in Scripture, which stresses that salvation is not granted based on human merit or effort but through the finished work of Christ. In Romans 5:15-21, Paul contrasts our sinfulness with the free gift of grace through Jesus, highlighting that our justification comes by faith alone. Moreover, the story of the lepers in 2 Kings 7 serves as a powerful metaphor; they did nothing to deserve the bounty of food that was provided by God. This illustrates that salvation and grace are gifts that we receive, reinforcing that no one can earn their way to God, thus validating the idea of grace as a free gift.
