About what should we pray?

Alma 34:17-28

Alma 34:17-28
17. Therefore may God grant unto you, my brethren, that ye may begin to exercise your faith unto repentance, that ye begin to call upon his holy name, that he would have mercy upon you;
18. Yea, cry unto him for mercy; for he is mighty to save.
19. Yea, humble yourselves, and continue in prayer unto him.
20. Cry unto him when ye are in your fields, yea, over all your flocks.
21. Cry unto him in your houses, yea, over all your household, both morning, mid-day, and evening.
22. Yea, cry unto him against the power of your enemies.
23. Yea, cry unto him against the devil, who is an enemy to all righteousness.
24. Cry unto him over the crops of your fields, that ye may prosper in them.
25. Cry over the flocks of your fields, that they may increase.
26. But this is not all; ye must pour out your souls in your closets, and your secret places, and in your wilderness.
27. Yea, and when you do not cry unto the Lord, let your hearts be full, drawn out in prayer unto him continually for your welfare, and also for the welfare of those who are around you.
28. And now behold, my beloved brethren, I say unto you, do not suppose that this is all; for after ye have done all these things, if ye turn away the needy, and the naked, and visit not the sick and afflicted, and impart of your substance, if ye have, to those who stand in need--I say unto you, if ye do not any of these things, behold, your prayer is vain, and availeth you nothing, and ye are as hypocrites who do deny the faith.
