Psalm 141 is presents the reality that even the holiest of saint has the potential to be the most horrific of sinners. The closer one draws to God, the more aware he or she becomes of their potential to sin. The psalm demonstrates that if one toys with sin, it will overtake them. Thus David, prays to God to guard his mouth and lips, to turn his heart from evil, and to protect against the allurement of the delicacies of those who work iniquity.
In Psalm 57, David experiences calamities coming from an enemy who is like a lion out for the kill. Although his enemies have set traps for him, David is confident that they will fall into their own traps. Hiding under the “shadow of His wings,” David knows that God will protect and deliver him.
As the Bible unfolds, little by little, it reveals a spiritual battle raging behind our earthly struggle. As Christians we are engaged in this spiritual battle. Our enemies are the world, the flesh, and the devil... and they are subtle in their disguises. Like Israel, we need to know how to fight. Psalm 47 provides us with the how to fight. We fight with praise to God, because our God reigns.
