The topic of grace has gained recent attention in positive psychology research, though little empirical work has been done to explore how religious individuals understand and experience grace. Using grounded theory, this study involves a secondary analysis of qualitative findings from seven doctoral dissertations conducted with Christians of various denominations. Four characteristics of the interviews were noted, exploring how they varied in depth, individual differences, grace distinctions, and coherence. These were followed by a detailed analysis of the eight uncontroversial components of grace uncovered in the interviews: Expression of God's love, unmerited, God's initiative, gift, abundance, relational, acceptance, and incomprehensible. Finally, we addressed the controversial aspects of a Christian experience of grace pertaining to how participants understand the work of Jesus in relation to God's gift of grace. A general definition of grace, based on the lived religious experience of these Christian participants, is, "the unmerited expression of God's love, in which God offers the gift of relationship with Godself." We also suggest a more particular definition for those who link grace with sin, separation, and the atoning work of Jesus, "the unmerited expression of God's love, in which God offers the gift of relationship with God through the atoning work of Jesus, whose death on the cross allows for the forgiveness of sins which separated people from God.
