I feel this is an oversimplification. I think these phrases may come in any order, which means we might not always find ourselves first facing a crisis. I grew up in a Christian home; every Christmas, my grandmother would gift me a religious book. Had it been written in my childhood, I feel confident "Grace Revealed" would have found its way into the gift bag. Therefore, the concept of giving grace to others was simply a part of how I was raised to behave. Before reaching that age of accountability, my morality and behavioral patterns were built around this concept of showing God's grace in every action; there was no crisis to spur me. After reading "Grace Revealed", I think any crisis I faced even later in life would have to be considered minor at this point in comparison anyways. Christians are flawed people living in a flawed world, so there are constant crisis. There is also constant grace, and the constant intent to do right by others (if they truly do mirror Jesus).
Therefore, I don't see these 3 phases as being that of the development of a Christian. Things can be going great, such as they were for the lawyer in "Grace Revealed", and it still isn't enough without God. Things can be going horribly, as they were for the soldier in Vietnam, but he was still paying the grace forward without knowing until years later why his actions were important. While I think all Christians might experience each of these, I don't think they always go in this same cycle. They ebb and flow.
