LilyM;4360920:
And I suppose you think there’s nothing else by way of good works or penances that can serve to mitigate our purgatory - for example putting up graciously with the irritations offered daily by coworkers, clients, spouse or children? Suffering patiently when we are ill? Suffering martyrdom, in ways great and small, for His sake? Giving alms to the poor? Fasting and abstinence as we are commanded to do in Lent?
In other words no-one lacks opportunities to pay off their sin debt ‘to the last penny’, as Christ said we all must. Prayer is only one means by which we can do so.
You’ve actually made my point for me : it’s precisely because I believe that enduring whatever suffering goes with one’s state in life, giving alms to the poor and so on are so important that I query the stress laid on saying prayers and the seeking out of indulgences.
When Our Lord spoke about the Last Judgment, were the people separated into two groups according to whether they fed the hungry and so on, or whether they said a lot of prayers?

Scripture is loud and clear on the importance of plenty of prayer. Firstly look at the behaviour of Jesus Himself, and the Apostles. Their example demonstrates the importance of prayer - and they are our rolemodels in all things, no?
Now Jesus didn’t just pray - He PRAYED - as in forty days of
prayer (combined with fasting, note He didn’t fast alone, though He often prayed without fasting) in the wilderness to prepare for His ministry. Up all night praying prior to choosing the Apostles. Up all night praying in Gethsemane - and I think more than a few other occasions where He either got up very early to pray or stayed up all night in prayer.
Now one of the few direct requests the Apostles made to Him requesting His teaching was ‘teach us how to pray’ - clearly they recognised the significance and importance of prayer and wanted to learn Jesus’ secret. And they followed His example of plenty of prayer as well - praying long and hard. Nine whole days of fervent prayer by those same Apostles between the Ascension and Pentecost for starters.
Finally, and I don’t know how it could possibly be clearer, we have the words of St Paul who tells us to ‘pray UNCEASINGLY’. Not just to pray, or even to pray a lot, but UNceasingly.
But wait, there’s more. What is prayer? It is communication with God, no? We speaking to Him and listening in our hearts for His response? Why on earth do you think He would be pleased to see people in Heaven face to face who hardly ever or never bothered to converse or communicate with Him while on Earth?
And do such people honestly WANT to be in Heaven, for that matter? What exactly do you think we’ll be doing IN heaven? Revelations gives us a clue - unceasing (LITERALLY, as we can’t be literally unceasing in our prayer on Earth) prayer in praise of God! You want to get into Heaven, you have to start living as if it’s already here you know - in other words plenty of prayer.
