The Collect for this Sunday is good for our reflection:
"Grant us, we pray, O Lord our God,
the constant gladness of being devoted to you,
for it is full and lasting happiness
to serve with constancy
the author of all that is good.
Through our Lord Jesus Christ, your Son,
who lives and reigns with you in the unity of the Holy Spirit,
one God, for ever and ever.
The psalm is joyful (Ps 98:5-9) but the reading are preparing us for some hard things. But the Gospel ends by telling us the "not a hair on your head will be destroyed. By your perseverance you will secure your lives."
