How do we know we have truly tasted God's grace?

True tasting of God's grace is evidenced by a profound personal experience that leads to spiritual transformation. According to the sermon, it is not enough to merely know doctrinal truths; one must experience them intimately. If a person finds the message of the gospel and doctrines like election to be the sweetest thing they've ever known, this indicates they have tasted grace. Furthermore, the resulting desire to grow in holiness—laying aside malice, guile, and hypocrisy—is a practical outworking of having experienced God's grace. The transformation in behavior and desire to pursue Christ more fervently marks a genuine taste of His grace, as expressed in 1 Peter 2:1-3.
