Have been very blessed and look forward to pursuing this piece of work on how to mark Lent.
Lent typically hasn't been paid alot of attention in the protestant tradition, which mostly just means that it is hard to know what to do if one were to mark Lent. I can't hardly bring myself to say "celebrate" Lent, since it mirrors the time that Jesus spent in the desert fasting. But it is a substantially significant time for those who follow after Christ.
But without that knowledge of how to pass Lent, one hardly knows where to start.
This prayer guide is a superb start.
