Joshua 12-13, Psalm 145, Jeremiah 6, Matthew 20

Psalm 145
The title of Psalm 145, "A Song Of Praise," is fitting for the last five Psalms.  Each of the five is psalms of praise, even if this is the only one attributed to David.
Years ago, I saw Bruce Springsteen in the Cotton Bowl.  At one point in the concert, Bruce quit singing and held the microphone out toward the crowd.  It seemed everyone was singing his song back to him.  At the time, I thought what an ego trip that must be.  Can you imagine having that number of people singing your song to you?
It is worthwhile to notice and highlight why the Psalmist says the LORD is worthy of praise.  Use those words and phrases as you worship and pray, for by using God's words to praise Him, we are doing the same thing to One who is truly worthy of praise and worship. 
Jeremiah 6:1-30
Would you compare Psalm 145 to Jeremiah 6 as light and dark, joy and misery, hope and despair, and life and death?  It is difficult if not disheartening reading these two chapters consecutively.  How did the people of Israel go from extolling the glory of God to refusing to listen to Him?
What has to occur to go from "The LORD is faithful in all his words" in Psalm 145:13 to "the word of the LORD is to them an object of scorn; they take no pleasure in it" in Jeremiah 6:10?  How did the people of Israel reach the point of saying "We will not walk in Your way" when David said, "The LORD is righteous in all his ways." 
Psalm 145:18 provides insight into what happened; "The LORD is near to all who call on him, to all who call on him in truth."  Instead of calling on the LORD, the people in Jeremiah's day "have not paid attention to my words; and as for my law, they have rejected it. (Jeremiah 6:19).  "They are all stubbornly rebellious...all of them act corruptly." (Jeremiah 6:28)
In 1 and 2 Kings and 1 and 2 Chronicles, David is the standard to which all the other kings of Judah is compared.  Needless to say, we will find very few who meet his example.  Instead, in Jeremiah's time "For from the least to the greatest of them, everyone is greedy for unjust gain; from the prophet to priest, everyone deals falsely."  "I set watchmen over you, saying 'Pay attention to the sound of the trumpet!'  But they say, 'We will not pay attention.''  Those who had the responsibility to lead the people in God's ways did not.
Lord God, I want to live Psalm 145 even if it seems the world in which I live in is more like Jeremiah 6.  Please raise up leaders who, like David, worship You.  Holy Spirit cause the Father's children to rejoice in the knowledge that He is faithful in all His words and kind in all His works.  Teach us to walk in the light, as children of light.
