In my attempt to answer my own questions regarding prayer, I think it behooves me to take a long look at the prayer Jesus taught the disciples when they asked him to teach them to pray.

Luke 11:1-4 Now Jesus was praying in a certain place, and when he finished, one of his disciples said to him, “Lord, teach us to pray, as John taught his disciples.”

And he said to them, “When you pray, say:

“Father, hallowed be your name.
Your kingdom come.
Give us each day our daily bread,
and forgive us our sins,
for we ourselves forgive everyone who is indebted to us.
And lead us not into temptation.”

Matthew 6:9-13
Pray then like this:
“Our Father in heaven,
hallowed be your name.
Your kingdom come,
your will be done,
on earth as it is in heaven.
Give us this day our daily bread,
and forgive us our debts,
as we also have forgiven our debtors.
And lead us not into temptation,
but deliver us from evil.

From the Heidelberg Catechism:
Why did Christ command us to address God thus: Our Father?

To awaken in us at the very beginning of our prayer that childlike reverence for and trust in God, which are to be the ground of our prayer, namely, that God has become our Father through Christ, and will much less deny us what we ask of Him in faith than our parents refuse us earthly things.

Matt. 7:9-11
Or which one of you, if his son asks him for bread, will give him a stone? Or if he asks for a fish, will give him a serpent? If you then, who are evil, know how to give good gifts to your children, how much more will your Father who is in heaven give good things to those who ask him!

Luke 11:11-13
What father among you, if his son asks for a fish, will instead of a fish give him a serpent; or if he asks for an egg, will give him a scorpion? If you then, who are evil, know how to give good gifts to your children, how much more will the heavenly Father give the Holy Spirit to those who ask him!

I Peter 1:17
And if you call on him as Father who judges impartially according to each one’s deeds, conduct yourselves with fear throughout the time of your exile,

Isa. 63:16
For you are our Father,
though Abraham does not know us,
and Israel does not acknowledge us;
you, O Lord, are our Father,
our Redeemer from of old is your name.
