1 Peter 1:10-16 / Mark 10:28-31
Between a book and a movie that is made out of it, more than a slight majority would say that the book is better.
But if we had read the book, then going to see the movie may just be a case of seeing how faithfully the movie had portrayed the book.
On the other hand, if we had only seen the movie, we may not bother to take the time to read the book. After all we had seen the action, so there is no need to read the composition.
The Old Testament prophets wrote about the coming of the Saviour. They had to be sensitive to the promptings of the Spirit as they wrote their prophecies.
They had to write about the sufferings of Christ and the glories that would come after them, and they tried to find out at what time and in what circumstances all that was to be expected.
It was like writing a book and wondering how and when the movie would be made out of it.
Anyway the prophets' task was to write the prophecies about the Christ. They may not have expected to see their prophecies fulfilled, nor to see the Christ in the flesh.
As for us, we know that Christ already came and fulfilled the prophecies. So, as the 1st reading would tell us, we are to free our minds of encumbrances, control them, and put our trust in nothing but the grace that has been given us through Christ.
And then we will be able to fully follow Christ and leave aside what is unnecessary or even hindering our lives, so that we will truly be holy in all we do, and finally to be able to see Christ face to face.
