In the second reading, the word of God is said to be sharper than a double-edged sword. This had always been a favorite verse of mine in my youth. When faced with a nightmare, I would recite the verse and find a sword in my dream-self's hand, which is pretty cool on its own. As an adult, this verse has combined with the warning of double-edged swords being a danger to their wielders. People, including myself, need to be careful about using God's word, especially when passing judgment.
The first reading tells us that wisdom is the greatest possession which we could have. Meanwhile, the Gospel tells us to give up all of our possessions if we wish to enter heaven. Normally, my father is a little uncomfortable with my Sunday reflections, but I know that he's in agreement with Jesus on this one. For our move to Alaska, we sold, gave away, or trashed over a third of what we owned. Of that, a good portion is sitting in my parents' house. My father has been encouraging us to throw it all away. I find it easiest to agree with him when it's not my stuff that he's talking about.
For me, it's not necessarily the physical possessions that I think are holding me back, but the mental baggage and bad habits that I keep with me despite knowing how they separate me from God. These are the things which are so hard to give up that I fear I may never do so. Although, I usually rationalize that since we take none of it with us in the end, I might as well enjoy them now. It's not the holiest thought, but I'm not the holiest person either.
