From my understanding - grace is a free gift that we enter into more fully through prayer and sacrifice. We do not bend God’s will no matter how much we pray.
In other words, we don’t pray to receive. It’s not a give and take relationship such as - “I pray this many times or I obey these many commandments and God saves my loved one or gives me what I’m praying for.”
How does this reconcile with the idea of promises attributed to certain prayers/novenas?
And - how do we reconcile this with passages such as "“If you abide in Me, and My words abide in you, ask whatever you wish, and it will be done for you.”
It would seem to me, slightly sacreligious to pray to God for superficial things such as a car - or even for someone’s health, because, either way, it will be God’s will and not our own in the end.
