1 Corinthians 1:17-25 / Matthew 25:1-13
The term "simple truths" may give the impression that truth is simple enough to be immediately understood.
That may be the case in a logical truth, like the saying "what you sow is what you will reap". This is clear and simple enough as a truth of life.
But there are also other simple truths that require some reflection in order to understand what that truth is.
Because what initially seems to be foolish from the human perspective may actually have the seeds of divine wisdom.
As St. Paul said in the 1st reading, the crucifixion of Christ cannot be expressed in terms of philosophy because the language of the cross is illogical from the human perspective.
The Jews demand miracles and the Greeks look for wisdom, and hence the crucified Christ does not make sense to them.
Yet, the foolishness of the cross is the power and wisdom of God, for God's foolishness is wiser than human wisdom, and God's weakness is stronger than human strength.
But to understand this, we have to look at the cross and the crucified Christ as the supreme expression of God's love for us.
When we understand how much God loves us, then we would want to be like lighted oil lamps which shine through the darkness of foolishness in search of God's wisdom.
Then we will also be willing to be like the oil that is being offered to be burnt and give out light for others. And that is indeed true wisdom.
