Ecclesiastes 3:1-11 / Luke 9:18-22
Whenever we talk about time, we may ask "What is the time?" or "How much time left?" if we are talking about duration.
If we are busy, we will say "No time ... " or "Don't have time ... "
But when the 1st reading talks about time, it is talking about a significant meaning of time.
It is time that belongs to God and that He is in control of the situations in whatever time they are happening.
It may be a time of happiness or a time of sadness, a time of hope or a time of despair, a time of joy or a time of tears.
We may not fully comprehend or understand the meaning of a particular period of time, but we still must believe that God is present in those times.
As to why God lets something happen, the 1st reading tells us that all God does is apt for its time.
Though God has permitted man to consider time in its wholeness, man cannot comprehend the work of God from beginning to end.
Neither did Peter fully understand what he was saying when he said that Jesus is the "Christ of God".
But in time he will find out and understand what he said.
We too will come to find out and understand why things happen the way they happen.
We only need to believe that all time belong to God and all that happens happen for a reason which we may come to comprehend and understand.
