Three times in his second epistle Peter exhorts believers thus:

applying all diligence, in your faith supply…(1:5)
be all the more diligent to make certain about His calling and choosing you (1:10)
be diligent to be found by Him in peace, spotless, blameless (3:14)

Diligence is to be an essential aspect of my life, having reference to my past (1:10), present (1:5), and future (3:14). This essential aspect of Christian living involves applied effort, reorganizing priorities, even a certain sense of regularity and habit.

In our experience-driven society that also influences Christians, that last bit of “regularity and habit” doesn’t sound too exciting or “wham!” “pow!” We want excitement, thrill, passion, zest, and fire.

This isn’t to say that living out the Christian life isn’t “exciting,” but that’s not the point of living an increasingly Christ-like life (1:5) that provides assurance one is among the elect (1:14) and anticipates the imminent return of Christ (3:14).

When our expectations of what Christianity should be like are formed by this world’s expectations of living we’ll either be greatly disappointed or end up adjusting the things of the Lord to give us the experience we want.
