And an article on "What should we pray for?", by the same author.

For you, O LORD of hosts, the God of Israel, have made this revelation to your servant, saying, 'I will build you a house.' Therefore your servant has found courage to pray this prayer to you. And now, O Lord GOD, you are God, and your words are true, and you have promised this good thing to your servant. Now therefore may it please you to bless the house of your servant, so that it may continue forever before you. For you, O Lord GOD, have spoken, and with your blessing shall the house of your servant be blessed forever."
(2Sa 7:27-29)

And the LORD said to him, "I have heard your prayer and your plea, which you have made before me. I have consecrated this house that you have built, by putting my name there forever. My eyes and my heart will be there for all time.

Rejoice in hope, be patient in tribulation, be constant in prayer.

Therefore, confess your sins to one another and pray for one another, that you may be healed. The prayer of a righteous person has great power as it is working.

For the eyes of the Lord are on the righteous, and his ears are open to their prayer. But the face of the Lord is against those who do evil."
