A Briefer Note on Motivations

In preparation for an upcoming church class on baptism I came across the following words of Robert Jenson. I thought it related to my own discomfort around motivations,
After baptism, it is too late for promises to do better, too late for 'getting myself together,' too late for guilt to be of use. The baptized have their lives to live after the effective and specific hearing of the final judgment. Therefore their moral life is the common life of those who are past having anything to lose or gain in their relation to their fellows. It is the common life of those for whom ulterior motivations and mitigations, while psychologically operative, are nevertheless morally irrelevant.
