At the yesterday Sunday mass, Fr. Jack talked about trials by God in two stories for understanding John 15:2: "Every branch in me that does not bear fruit he takes away, and every branch that does bear fruit he prunes, that it may bear more fruit". Why does He prune vine branches? First, he referred to a popular passage in Psalm 12:6, "The words of the LORD are pure words; as silver tried in a furnace on the earth, purified seven times". In the Gospel, "a firmer is the Father, a vine tree is Christ, grapes are the faithful, and branches are all of us", Fr. Jack said. Father is kind to purify us as gold is thrown into fire and becomes pure gold seven times with various trials. Second, he showed us with a different story. "An oyster swallows sand in saltwater, and it stands anguish to bring a beautiful pearl into the world". You live in a sea of trials like that oyster. You encounter many difficulties and survive them. Finally, your challenges to the difficulties make fruits of beautiful pearls at the end of the day. His preach is really beautiful and simple to shake my heart and soul. I am deeply moved at the preach yesterday.
