As much as eating is something we do everyday, yet whatever we are eating is not to be taken in without discernment.
Certainly, we must give thanks to God for the food that we are to consume.
But we also must be careful about what we are going to eat. Food that is spoilt or expired is not to be eaten otherwise we will end up with a bad tummy.
As it is said, we are as healthy as what we eat, or don't eat.
If what goes into the stomach affects our physical health, then what goes into our hearts will affect our spiritual health.
In the 1st reading, the fruit of the tree of knowledge of good and evil was obviously not just an ordinary fruit but it was a forbidden fruit, and eating of it had spiritual consequences.
In the gospel, Jesus made it clear that while all food is good for the body, it is what goes into the heart that has spiritual consequences.
So as much as we discern whether the food that we are about to eat is good or not for us, we must be even more discerning about what goes into the heart by what we see and hear.
Let us keep our hearts clean and pure, a heart that is pleasing to God, so that our hearts will bear good fruits for the glory of God.
