Passage
Their heart is as callous as the fat, but I delight in your law.
Their heart is as callous as the fat, but I delight in your law.
Psalms 119:68 You are good, and do good. Teach me your statutes.
Psalms 119:69 The proud have smeared a lie upon me. With my whole heart, I will keep your precepts.
Psalms 119:70 Their heart is as callous as the fat, but I delight in your law.
Psalms 119:71 It is good for me that I have been afflicted, that I may learn your statutes.
Psalms 119:72 The law of your mouth is better to me than thousands of pieces of gold and silver.
The verse centers on "light", "heart", "callous", and "delight". It is saying that the verse draws attention to "light" and "heart", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 69's "The proud have smeared a lie upon..." into verse 71's "It is good for me that I...", so "light" and "heart" belong inside that flow. In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "light" and "heart" with trust shaped by these words, not by a vague optimism outside the passage.
