Isaiah 55:10-11 / Matthew 6:7-15
Every now and then, we hear of this so-called proverb - What goes up must come down (Isaac Newton), and what goes down must come up.
Whether it is about physics or gravity, we can generally understand this proverb in the reality of life.
Whether it is the share market or the fortunes of life or even the cycle of life, it always go one way or the other. Nothing remains stable or constant throughout.
The 1st reading may also be saying something like this. "As the rain and the snow come down from the heavens and do not return without watering the earth ... "
But it goes on further to say that the Word of God does not return to God empty, without carrying out God's will and succeeding in what it was sent to do.
In Jesus is the Word of God made flesh. And in the gospel, He cautioned about the use of too many words without paying meaning and attention to what is said.
Hence He taught the prayer of the "Our Father" or what is also called the Lord's Prayer.
Just like God's Word came down to earth and carried out God's will and fulfilling what it was sent to do, then the same happens when we pray the "Our Father".
Our words go up to heaven and is heard by God our Father. And from heaven, God sends forth His blessings to fulfill our needs and His forgiveness for our sins.
Yes, what goes down must come up, and what goes up must come down. Hence let us pay attention to what we say, and mean what we pray.
