Passage
Let us lift up our heart with our hands unto God in the heavens.
Let us lift up our heart with our hands unto God in the heavens.
Lamentations 3:39 Wherefore doth a living man complain, a man for the punishment of his sins?
Lamentations 3:40 Let us search and try our ways, and turn again to the LORD.
Lamentations 3:41 Let us lift up our heart with our hands unto God in the heavens.
Lamentations 3:42 We have transgressed and have rebelled: thou hast not pardoned.
Lamentations 3:43 Thou hast covered with anger, and persecuted us: thou hast slain, thou hast not pitied.
The verse centers on "lift", "heart", "hands", and "heavens". It is saying that the verse draws attention to "lift" and "heart", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 40's "Let us search and try our ways..." into verse 42's "We have transgressed and have rebelled thou...", so "lift" and "heart" belong inside that flow. In Lamentations context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "lift" and "heart" with trust shaped by these words, not by a vague optimism outside the passage.
