God hears the prayers of the faithful worshiper.
In David’s lament, he directs his prayer toward heaven in expectant faith. The mention of morning and sacrifice suggests that his prayer “comes in the context of a faithful worshiper who receives assurance and expresses personal consecration by way of these ordinances; it is small wonder that such a person will watch, looking around and ahead in expectant faith” (from the ESV Study Bible). Let this wallpaper remind you to prayer early, expectantly, and faithfully.
“Give ear to my words, O LORD; consider my groaning. Give attention to the sound of my cry, my King and my God, for to you do I pray. O LORD, in the morning you hear my voice; in the morning I prepare a sacrifice for you and watch.” (Psalm 5:1-3)
