Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all comprehension, will guard your hearts and your minds in Christ Jesus.

 "Beware in your prayers, above everything else, of limiting God, not only by unbelief, but by fancying that you know what He can do. Expect unexpected things, ‘above all that we ask or think’. Each time, before you Intercede, be quiet first, and worship God in His glory. Think of what He can do, and how He delights to hear the prayers of His redeemed people. Think of your place and privilege in Christ, and expect great things!" (Andrew Murray) 

 "Lord, Thou sendest down rain upon the uncounted millions of the forest, and givest the trees to drink exceedingly. We are here upon this isle a few handfuls of men, and how many myriads upon myriads of stalwart trees! Teach us the lesson of the trees. The sea around us, which this rain recruits, teems with the race of fish; teach us, Lord, the meaning of the fishes.  Let us see ourselves for what we are, one out of the countless number of the clans of thy handiwork. When we would despair, let us remember that these also please and serve Thee."  (Robert Louis Stevenson-Vailima Prayers and Sabbath Morn) 

 "I ought not to omit any of the parts of prayer—confession, adoration, thanksgiving, petition, and intercession. There is a fearful tendency to omit confession, proceeding from low views of God and his law, slight views of my heart and the sins of my past life. This must be resisted. There is a constant tendency to omit adoration, when I forget to whom I am speaking-when I rush heedlessly into the presence of Jehovah, without remembering His awful name and character—when I have little eyesight for His glory, and little admiration of His wonders.  'Where are the wise?'  I have the native tendency of the heart to omit giving thanks.  And yet it is specially commanded, Philippians 4:6.  Often when the heart is selfish, dead to the salvation of others, I omit intercession. And yet it especially is the spirit of the great Advocate, who has the name of Israel always on His heart. Perhaps every prayer need not have all these; but surely a day should not pass without some space being devoted to each."  (Robert Murray M' Cheyne)
