Do not disdain the discipline of the Lord

From today's mass readings, from the Letter to the Hebrews (Ch. 12:5-7, 11-13):

Brothers and sisters,
You have forgotten the exhortation addressed to you as children:
“My son, do not disdain the discipline of the Lord
or lose heart when reproved by him;
for whom the Lord loves, he disciplines;
he scourges every son he acknowledges.”
Endure your trials as “discipline”;
God treats you as sons.
For what “son” is there whom his father does not discipline?
At the time,
all discipline seems a cause not for joy but for pain,
yet later it brings the peaceful fruit of righteousness
to those who are trained by it.

So strengthen your drooping hands and your weak knees.
Make straight paths for your feet,
that what is lame may not be disjointed but healed.

God disciplines us as does a loving Father, a discipline that at times seems a cause "not for joy but for pain" but later "brings the peaceful fruit of righteousness". It trains us and forms us. How awesome God is!
