It is not funny that anything else should fall down; only that a man should fall down.... Why do we laugh? Because it is a gravely religious matter: it is the Fall of Man. Only man can be absurd: for only man can be dignified.
(Gilbert Keith Chesterton (1874-1936), British author. "Spiritualism," All Things Considered (1908).)
'Discernment, as a talent, requires development and maturity to fully understand, then the integrity to follow through on what you have discerned'
Discernment w/o development = a funny feeling
Discernment w/o maturity = rash judgements
Discernment w/o integrity = good intentions never exercised
Discernment is both a gift and a talent, depending on the individual and the circumstances.
A spiritual gift is given to those who accept the gift of salvation, but that gift needs to be developed. Through a vibrant and active relationship with Jesus Christ. (Not everyone receives the same gift)
All who accept Christ are given gifts that are ultimately about our unique ability to glorify him and further the spreading of the Gospel of Jesus Christ. It is for you to serve others and the kingdom.
It can be used to discern who is of Him, but it can also be used to discern what his will is for your life.
As a talent, it is something that can be developed in all, especially those how believe in him. A talent can be used for spiritual and non spiritual needs. It is a matter of genetics and environment.
All of us are called to use discernment, some have this as a specific gift, with a specific God given purpose.
