This verse makes me think of Job in his trials. When our soul "cleaves to the dust," where do we turn? "Quicken" gives the idea of living and reviving. Do we turn to God's Word to lift us up? to give us new meaning to our life? As Hebrews 4:12 explains, "For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart." God's Word is alive and it has the power to make us alive and revived again.
(26) I have declared my ways, and thou heardest me: teach me thy statutes.
It is not wrong to tell our ways to the Lord. Proverbs 16:9 says, "A man's heart deviseth his way: but the Lord directeth his steps." God knows all of our ways anyway, and He is able to direct our steps. If our ways are not in line with His ways, He is able to lead us to be in line - to teach us His statutes.
(27) Make me to understand the way of thy precepts: so shall I talk of thy wondrous works.
This verse seems to correlate with two previous verses: "Blessed art thou, O LORD: teach me thy statutes." (Psalm 119:12), "Open thou mine eyes, that I may behold wondrous things out of thy law." (Psalm 119:18) God is willing, ready to teach us His ways. But are we ready to receive it? Are we willing to understand the way of His precepts? To the heart that is willing to learn, God is more than willing to teach.
The more we learn God's ways, the more we should be talking of His wondrous works.
(28) My soul melteth for heaviness: strengthen thou me according unto thy word.
Similar to verse 25 ("My soul cleaveth unto the dust: quicken thou me according to thy word."), we must recognize that God's Word is able to strengthen. There will be days when our soul "cleaves to the dust" or "melts for heaviness." As believers, we are not exempt from these days. But do we use these days to strengthen our reliance on Jesus Christ and His Word?
