This saying is trustworthy

If we have died with him
we shall also live with him;
if we persevere
we shall also reign with him.

But if we deny him
he will deny us.

If we are unfaithful
he remains faithful,
for he cannot deny himself.

(from today's Epistle - 2 Timothy 2:8-13)

Lord Jesus Christ, Son of the living God, have mercy on me - a sinner
