Psalm 86 begins with a plea to the Lord for help, a plea not based on anything done to deserve help but rather on the nature of the Lord--good, forgiving, and abounding in steadfast love. The psalmist continues by recording the unique greatness of the Lord, and how everybody--all nations--recognize this greatness.
In verse 11, we have two more requests: Teach me your way, O Lord, that I may walk in your truth; give me an undivided heart to revere your name. The psalmist wants to know more about God so as to live the kind of life that God would want. Moreover, to live that kind of life, the psalmist is going to have to give up other distractions.
After the requests come expression of gratitude including a reassertion of God's love and care.
When we are in our own times of difficulty, we can pray this psalm, we can ask for Lord's favor, because we also can remember the times that the Lord has helped us and comforted us.
