The Psalmist is humbly offering his imminent troubles up to God as a meal-offering of the evening sacrifice. He is reasoning with God that the genuine dangers that he resolutely faces are life-threatening. He is arguing that appropriately placing his life in God's guiding hands is as valuable as offering God a sacrifice or meal offering. The apostle says we resolutely face many trials in this life. These trials are intentionally allowed by God to reinforce our faith. But because we live in a ruined world in which Satan works against us we are susceptible to be severely harmed for life. The Psalmist describes this throughout the Psalms as a trap set by the wicked. 

The Psalms are not categorically a counseling book. They are not merely recorded to pass on mutual encouragement. The Psalms are more than direct encouragements for God's elect. They are composed in pronouncements and cries to direct us in a way to escape the trap or the wound that will scar us for life. The Psalms are heartfelt pleas for us to go from one miraculous deliverance to another. Like the Psalmist faced death in the heat of the battle, comparing the wars of Israel with the daily responsibilities of public life.

 We are sufficiently instructed in Psalms 1 that if we do not meditate on the eternal law, covenants, curses, comprehensive statutes, sacred promises and divine decrees that we will be drawn away by the counsel of the wicked, into the path of the wicked, and sooner or later be comfortable sitting in the seat of scoffers. The Psalms are written to know ourselves and God.

The Psalmist is teaching he avoids pronouncing words that promote the culture that will ultimately trap the saints. He daily approaches God in the words of the law, covenants, etc. This is why he says to "set a guard over my mouth."The words articulated in this world promote a culture of danger that will trap the saints. You carefully mark down how the world treats the handicap. You invariably see God intentionally turns the world upside down to relentlessly focus on the weak and helpless.

 We naturally think the world is operated by daily activity and work. But the Psalms inform us that the tangible world represents a war of desires. It is a miraculous creation of God that is morally opposed to the violent desires of the wicked. Every man is who he is by the images that he composes. This why the Psalmist prays when facing the potential traps as desires of the wicked." Do not grant the wicked their desires, O LORD; do not let their plans succeed, or they will become proud." Consequently, the Psalms are pronouncements that fashion the world through righteous desires. The Psalmist is teaching the prayers offered to God in these pronouncements are the way that he communicates. They extricate him from the words spoken in the world that create traps for the helpless. The Psalms are given to redeem God's people.
