How do we know grace is true in the context of Arminian belief?

In Reformed theology, grace is defined as the unmerited favor of God towards sinful humanity, rooted in God's sovereign will. This stands in stark contrast to Arminian beliefs that emphasize human free will and the ability to choose salvation. Evaluating expressions of grace in those who may hold Arminian views requires us to focus on their profession and acknowledgment of God’s role in salvation. While they may profess faith in God, a true understanding of grace must reflect God's sovereignty in choosing His people, as articulated in Scriptures like Ephesians 1:4-5.
