People of all faiths and philosophies pray about their needs.  And they hope God will answer them.  Jesus taught, “Your Father knows what you need before you ask Him.”  In the first chapter of Science and Health, Mary Baker Eddy expands on the idea of an all-knowing and all-loving God.

The prayer that reforms the sinner and heals the sick is an absolute faith that all things are possible to God, — a spiritual understanding of Him, an unselfed love. Regardless of what another may say or think on this subject, I speak from experience. Prayer, watching, and working, combined with self-immolation, are God’s gracious means for accomplishing whatever has been successfully done for the Christianization and health of mankind

Thoughts unspoken are not unknown to the divine Mind. Desire is prayer; and no loss can occur from trusting God with our desires, that they may be moulded and exalted before they take form in words and in deeds. (p. 1:1–14)

God is not moved by the breath of praise to do more than He has already done, nor can the infinite do less than bestow all good, since He is unchanging wisdom and Love. We can do more for ourselves by humble fervent petitions, but the All-loving does not grant them simply on the ground of lip-service, for He already knows all.

Prayer cannot change the Science of being, but it tends to bring us into harmony with it. Goodness attains the demonstration of Truth. (p. 2:8–17)

Who would stand before a blackboard, and pray the principle of mathematics to solve the problem? The rule is already established, and it is our task to work out the solution. Shall we ask the divine Principle of all goodness to do His own work? His work is done, and we have only to avail ourselves of God’s rule in order to receive His blessing, which enables us to work out our own salvation. (p. 3:4)
