The title of this Psalm describes this as being written when the LORD had delivered David from the hand of all his enemies. We know David was a warrior king who dealt with enemies without and within the nation of Israel most of his life. 2 Samuel 23 begins with, "Now these are the last words of David," and 2 Samuel 22 is almost identical to Psalm 18. So it appears quite likely, David wrote this song looking back at all the LORD has done over the course of his life.
I have spoken of my inadequacy to describe the multifaceted God we worship and serve entirely, but David does a fantastic job in this Psalm. Just look at all the descriptions he uses to describe LORD in the first two verses with the personal pronoun "my" attached. David experienced the LORD fulfilling all these descriptions. His vivid portrayal of his likely death and God's deliverance in verses 4-19, depicts his awesome God.
David knew what it meant to worship God, didn't he? Even as he describes his desire and attempt to live by God's righteous instruction in verses 20-24, he credits God with being the light who lit his darkness, the reason he defeated his enemies, and the One who made him blameless.
As I read David's list of accomplishments and his crediting it all to God's mercy, I thought of Paul. He says the same thing in Philippians 4:13, "I can do all things through him who strengthens me" and 1 Corinthians 15:10, "By the grace of God I am what I am, and his grace toward me was not in vain. On the contrary, I worked harder than any of them, though it was not I, but the grace of God that is with me."
I desire, like David, to look back on my life and worship all my great LORD and God has done in and through me. I will sing His name and His praise. He is my great salvation. He has shown His steadfast love to me.
Oh, LORD my God, may my worship of You be as complete as David's. May I also be a man after Your own heart.
2 Thessalonians 3:6-14
Notice the reason for Paul's instruction to keep away from an idle brother (v 6) and from a brother who does not obey the instruction of this letter (v 14). The command is given in the hope the believer will become ashamed of their action or inaction.
Shame is not a word used very often in our culture, but it is in the Bible. In Luke 13:10-17, Jesus confronted the hard-hearted ruler of the synagogue, who was upset because He healed on the Sabbath. Verse 17 says because of Jesus' rebuke, His adversaries were put to shame. In Ezra 9:1-15, Ezra describes the shame he and the nation had brought upon themselves. In Ezra, the result of this shame is the repentance of the nation. Luke 13 does not record the ruler of the synagogue's repentance, but that was Jesus' desire.
Is shame a part of repentance? Should we be ashamed before God for our sin? It seems Adam and Eve felt shame after eating the fruit of the tree of the knowledge of good and evil. In Genesis 2:25, both were naked and were not ashamed, yet after sinning against God, they tried to cover themselves by sewing fig leaves together. They went from unashamed to ashamed because they did not keep God's instruction.
Jesus, I know the shame of the cross was a shame I should have borne, not You. Holy Spirit, I realize my insensitivity to shame. It is easy to blame it on the culture in which I live. However, I must remember I am a foreigner here, my citizenship is in heaven, and I should be ashamed of those things in my life that are in opposition to the character of my King. Please sensitize me to be ashamed of those things in my life worthy of embarrassment before my Savior and Lord.
