A better question would be in what way is prayer
not effective. As Jack Hayford writes,
Supplication moves into the confusion of the fallen order of things (e.g., a broken heart, a broken home, someone’s broken health) and begins through supplication to bind up broken things, drawing the strands of such binding back to what ought to be according to God’s intent and God’s will.
In short, the praying Church has been empowered by Christ’s promise to pray in ways that stop what hell’s councils are trying to advance.
With specific reference to intercession, Hayford writes,
Therein lies the idea of intercession. What seems random— catching us unexpectedly in time and circumstance and commanding our attention— is not accidental but providential.
Dear one, almost every day of our lives, you and I step into apparently random situations. If we perceive they are ordained of the Spirit, we will learn to respond to them , knowing God has brought us to them. There will be occasions when we will have a seemingly random thought, or a “signaling,” which might seem accidental ; but wisdom will teach us to seize these moments as intended by God to cause us to intercede for someone or some situation.

The last statement is important. We are not acting on our own but through the ministry of prayer are being caught up in the work of the Trinity, in which both Christ and the Holy Spirit intercede for us.

Well let me rephrase that for you. When someone asks you to pray for them why don’t you ask them to just pray to God themselves? Why do they need you to pray for them? Will it do any good? And if so, what good will it do?
Because God works through our prayers. The Holy Spirit intercedes through us. As we pray the perfect will of the Father, “all things work together for good” as Romans 8 states.
2 Corinthians 10:3-4 states, “For though we walk in the flesh, we are not waging war according to the flesh. For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds.” Prayer is one of the most powerful weapons the Christian has.
Do you believe that we will participate in the divinity of God when we reach heaven? Why do you believe that the saints in heaven cannot hear your prayers? Even your Grandma? I ask my mother and my brother to pray for me all the time, just as if they were standing next to me.
It’s not that I don’t think they can. It’s that I cannot communicate with them on this plane of existence.
He said more than that. He said “forgive us our trespasses as we forgive those who trespass against us.” A very dangerous prayer to pray. This doesn’t say “only confess your sins to the Father”. It places a qualification on our own forgiveness. We must forgive if we are to be forgiven. The Church has never taught anything different.
The purpose of this story is to demonstrate that God’s mercy extends to everyone, even the despised tax collector, who in this case, was repentant. It has nothing to do with whether or not we should confess our sins.
None of that changes the fact that these are examples, given by Jesus, of confession of sin directly to the Father in prayer and in one case we have Jesus explicitly saying that justification results from this sincere confession.
Yes, this would be a very Catholic thing to say. Absolution is not pronounced until the confession is made. You seemed to be saying that absolution has already been pronounced.
It has been on the condition that we confess our sins. If we confess, we have assurance that we will be forgiven.
SteveVH;12428961Jesus did something else as well. He built a Church and specifically gave that Church the power and authority to forgive sin:
said:
"He breathed on them and said to them, "Receive the Holy Spirit. “If you forgive the sins of any, their sins have been forgiven them; if you retain the sins of any, they have been retained.”
(John 20:22-23)
Now, if Jesus meant us to confess our sins directly to God then why did he give his Church this authority? Keep in mind that this was only the second time that God ever breathed upon man. It was an important event, to say the least.
Well, if we interpreted this verse to mean what you say it means, he gave the disciples authority to forgive sin, which doesn’t necessarily equate to giving Catholic priests today authority to forgive sins.
