My girlfriend has been praying the Divine Mercy and prayed for the Lukewarm catholics.
Amazingly, last weekend, she was invited to go out to lunch with a couple who are non-Christians and invited a Catholic along with them.
The couple was asking my girlfriend about her life journey - they have not met for quite some years now - and my gf said about how she had been baptised and got closer to God.
The friend of the couple who is a Catholic but does not practice the faith much. She didn’t know how to pray the Rosary and Divine Mercy. Well, she was so asking my g/f many questions about Catholic faith and wanted to learn how to pray the Rosary and Divine Mercy.
My g/f had with her the pamphlets on how to do those two prayers

The lady now tries to learn how to pray.
My g/f had two other similar situations related to the Divine Mercy. One thing I know, she’s also got me into praying a lot (compared to my past)
