Call it transformation if you want, but the basic message of the gospel is one of change. God promised to change out our stony heart for one of flesh: the original heart transplant! (See Eze 36:26). We are told His Holy Spirit is changing us into the likeness of Christ. (See 2 Cor 3:18). Is that happening for you?
I know I’m not the same person I was some fifteen or twenty years ago. I grew up a very troubled young woman in a very troubled family. I spent quite a few years as a “basket case.” Today I’m incredibly happy, married, and professionally and personally successful. I’m sure no one who knows me now would call me troubled or a basket case!
