Final answer:
John 4:35 encourages lifting one's eyes to notice spiritual opportunities, unlike the physical act of lifting the cross depicted in the crucifixion story from Luke 23:34.
Step-by-step explanation:
According to John 4:35, what one should lift up is not a physical burden, such as the cross, but rather one's eyes to notice the fields ripe for harvest. This passage metaphorically suggests that there are opportunities ready for the taking, just as crops are ready for harvesting.
It focuses on spiritual readiness and evangelism, contrasting with the physical depiction of lifting a great weight as described in the reference to the crucifixion of Jesus, where various figures struggle to lift the cross in the scripture from Luke 23:34.
