What does Hebrews 5:7 mean?
Earlier verses explained that a priest offers prayers to God on behalf of the people. Here, Jesus is said to have done the same. In this way, He again fulfills the requirements of a human priest.The writer of Hebrews has also made mention of Psalm 22, which describes a sinless character crying out to God to be rescued (Psalm 22:24; Hebrews 2:12). Jesus' suffering on the cross brought literal fulfillment to the words of that Psalm. Some believe that the writer of Hebrews may also be referring to Jesus' prayers in the garden of Gethsemane prior to His arrest (Matthew 26:39; Luke 22:42). Jesus' death on the cross was the sacrifice offered, once and for all, for human sin (Hebrews 9:26).
Of course, Jesus was killed by those who arrested Him. The "rescue" He obtained was not from death, but out of death. The resurrection of Jesus was the ultimate sign of His acceptance and approval by God.
