Ecclesiastes 3:1-11 / Luke 9:18-22
Generally speaking, for something to work out, there must be the combination of the right place, the right persons and the right time.
These three factors can be said to be the legs of a three-legged stool, which can stand steady even in a uneven surface.
So when the combination of the right place, the right persons and right time come together, that is what we call the "appointed time", and we also know that it's not through human effort but rather it's the work of the divine.
The 1st reading talks about time and seasons for apparently cyclic human activities which at the same time are also apparently opposite in nature.
Yet as much as man may be able to comprehend what is happening at a particular time or season, yet he cannot comprehend the work of God from beginning to end.
And even in the gospel, when Peter said that Jesus is the Christ of God, he may not know the full impact of what he was saying nor for that matter of fact, all its consequences.
But in time to come, Peter and the rest of the disciples will come to know what the Christ of God came to do and how He would go about accomplishing it.
So let us also be aware that what we do now is a preparation for the future and has a consequence for the future.
Hence if what we do now is done in God, then we are preparing for the God's "appointed time". But if not, then we are only creating obstacles in the fulfillment of God's plan.
Let us remember that all time belongs to God, hence let us do what God wants of us ... all the time.
