The one word that keeps recurring in the 1st reading is the word "faith". It begins the passage as well as ends it off.
It talks about the faith of Biblical characters like Abel, Enoch and Noah.
By their faith they came to know who God is, and by their faith they experienced His presence, and it was by their faith they did God's will.
In the broadest sense of the word, faith can be said as believing in what cannot be seen and hoping in what cannot be fully explained.
In other words, faith is a gift from God to experience a mystery that is revealed and yet keeps revealing.
In the gospel, the disciples had their faith brought to another dimension when they saw the mystery of who Jesus is being revealed in His Transfiguration.
But still they don't understand what was meant "rising from the dead" and that Jesus will suffer grievously and be treated with contempt.
There may be still many things about our faith that we do not understand.
But still let us give thanks to God and hold firm to our faith. With faith, we will be able to see beyond the ordinary to a mystery in which God reveals Himself and will keep revealing Himself to us.
