David prays for two things -- (A devotion in one of CRBC's Prayer Meetings

Psalm 19:14 -- 'May the words of my mouth & the meditations of my heart, be acceptable in Your sight, O Lord, my Rock, & my Redeemer'

This Psalm teaches us wisdom in two divisions. On the one hand it helps us to see the non-verbal design of nature in telling the glory of God and on the other, the written words of the Bible in revealing the Lord's will to His people. The verse that may help us understand the unity of Ps.19 is found in v.6c, where it is said of the sun that 'there is nothing hidden from its heat.’ And in gazing & hearing these two great voices as they speak, David realizes and senses his own inadequacy before God. Because not only that there's no skin hidden from the sun's heat, there is also no heart that is not weighed by the word of God. Whether it is from hidden faults, presumptuous sins, or great transgression, the Psalmist sense his unworthiness, his failings; brethren, our hearts are layed open before the Lord's scrutiny. Moreover, He uses the word of God to convince us that we are not righteous enough and that we are not righteous thoroughly. That's why he prays for two things:

First, that the Lord may accept his sacrifice, ‘May the words of my mouth and the meditations of my heart, be acceptable in Your sight.' The word 'accept' is closely connected in the daily sacrifices of the temple like the lambs, goats & turtledoves commanded in the book of Leviticus. While Hosea in chapter 14 and verse 2 links it to the acceptable, repentant hearts: '...we will pay with bulls the vows of our lips', David prays here that his whole person be accepted by God even though he is unworthy.

Secondly, that the Lord may help and deliver him. The phrase 'My Rock’ is often used with warfare and military defenses, take for example the first lines of Psalm 18: ‘I love you, O Lord, my strength. The Lord is my rock and my fortress and my deliverer, my God, my rock, in whom I take refuge, my shield, and the horn of my salvation, my stronghold. I call upon the Lord, who is worthy to be praised, and I am saved from my enemies.’ It means that God shall fight for us, and He will give us the strength & grace to continue fighting sin. As for ‘My Redeemer' it is that the Lord as Deliverer shall pay for the ransom price against David's enemies. From the background of Old Testament motif of God’s redemption of Israel from Egyptian bondage, so it is now being appealed by David and Christians that they have the Lord as their Deliverer from sin & guilt.
