Praying confidently and with persistence

There is one difference that distinguishes prayer to God from prayers addressed to another person.

Prayer addressed to another demands a certain degree of familiarity from the outset, thanks to which one gains access to the person one is begging from.

Whereas prayer to God makes us, in itself, friends of God. Our souls are lifted up to him, lovingly converse with him, and adore him in spirit and truth (Jn 4,23).

This close relationship that is acquired as one prays prompts a person to apply himself to prayer with confidence.

Hence it is said in the psalm: “I call upon you,” that is to say, I have prayed with confidence, “for you have answered me, O God” (16[17],6).

Having been taken into close relationship with God through the original prayer, the psalmist then prays with increased confidence.

Thus, in prayer to God, diligence or persistence in asking is not an imposition but, rather, pleasing to God.

For the gospel says: “We should always pray and never grow weary”, and elsewhere the Lord invites us to make our requests: “Ask and you will receive, he says, knock and it will be opened to you” (Mt 7,7).


“Jesus told his disciples a parable about the necessity for them to pray always without becoming weary.

He said, “There was a judge in a certain town who neither feared God nor respected any human being.

And a widow in that town used to come to him and say, ‘Render a just decision for me against my adversary.’

For a long time the judge was unwilling, but eventually he thought, ‘While it is true that I neither fear God nor respect any human being, because this widow keeps bothering me I shall deliver a just decision for her lest she finally come and strike me.'”

The Lord said, “Pay attention to what the dishonest judge says.

Will not God then secure the rights of his chosen ones who call out to him day and night?

Will he be slow to answer them?

I tell you, he will see to it that justice is done for them speedily.

But when the Son of Man comes, will he find faith on earth?”” – Luke 18:1-8.
