Can a Christian walk away from God? To help work through this question, we must first recognize and accept that Christianity is not neat, and sin has never been respectful of our preferred categories. We also have to admit that this conversation is subjective in nature: we cannot know what is happening in a person’s heart or all the ancillary issues that contribute to why a person would “accept and reject” Christ. The Hebrew writer is suggesting there can be this kind of Christian—a believer who spurns the grace he once received for whatever reasons. What does that mean? How are we to think about friends who reject Christ?
