The biblical phrase, "the first shall be last and the last shall be first" may be rather confusing to many as it doesn't explain itself. This concept does hold three important lessons that we should understand for our self-examination in applying Christ's teachings in our lives. These teachings are given in the following verses: Mark 10:17-31, Mt 20:1-16, Luke 13:22-30, Matt 5:17-20, and Rev 20:6.
