The events of Luke 17 occur as Christ was traveling to Jerusalem where he would be crucified.  He taught four timeless lessons :  (Luke 17:1-4) “Be forgiving”.  The lesson of Christ began with “Be on your guard” (v3).  More accurately, “Take heed to  yourselves.”  We only get forgiveness when we forgive. The second lesson (vs 5-10) “Be humble,” begins with “mustard-seed faith” and ends with obedience as a minimum requirement.  If our faith is no greater than a mustard seed, and apparently it is not, we have little about which to boast. The third lesson is self-evident: “Be thankful.”  And the fourth we know but need to be reminded:  “Be ready.”,

If we learn the first three, be forgiving, be humble, be faithful, we will accomplish the fourth – be ready.
