I missed Mass this morning and read the Gospel reading for today from Matthew 13. Jesus explained to the disciples the parable of the weeds in the field. He mentioned the world, the Evil One, the Devil, the end of the age, angels, the collection out of his Kingdom all who cause others to sin and all evildoers ~ throwing them into the fiery furnace where there will be wailing and grinding of teeth, and the righteous shining like the sun in the kingdom of their Father. At the end, Jesus said, "Whoever has ears ought to hear."
Indeed, Jesus' words are life, the most important thing we'll ever hear. Listening to him or not can result in eternal life or eternal death. His words are especially acute with me now when I am constantly hearing about the deaths of many I personally knew and seeing so many other living friends who do not show any interest in knowing him or knowing him better.
Note that Jesus separated those who cause others to sin from all evildoers ~ we must avoid causing others to sin like the plague.
