Failure?

His ears vibrated by the piercing sound of the rooster's crowing, then his eyes were locked by the Savior's knowing look. Peter had failed - he had indeed denied The Lord (cf Lk 22:60, 61).  

Peter was shocked and sickened by his own weakness, "he ran outside and wept" (vs 62).  However, Jesus was not surprised at all, he knew Peter would fail - yet, he chose the fisherman anyway and would return to affirm him after his resurrection (cf Jn 21:15-19).  

When you fail - again, you may be surprised and sickened by your failure. But The Lord will be neither. Christ will be waiting to lift you up and affirm your place and your worth in his kingdom. 

You can't earn your place in the kingdom and you don't keep it that way either, it is "a gift of God" (cf Eph 2:8-9).  Instead, your work in the kingdom is a product of your place in it.

Each time you fail, each time you fall, instead of losing heart, take heart and thank The Lord for his gift of salvation as well as your place in the kingdom; and glorify Him by trying again. It's grace, after all, not grit.  Jus' Say'n.
