David Guzik: Though Jesus was God and is God, yet He learned obedience. God, enthroned in heaven’s glory, can only experience obedience by casting off the glory of the throne and humbling Himself as Jesus did. Surely, there is no need for “obedience” in Heaven because there is no “disobedience.” As God, Christ had access to divine omniscience and omnipotence. However, according to Scripture, He chose to experience human weaknesses such as hunger and fatigue. He also chose to experience learning and growth. In Luke, Jesus is said to have "learned" through His struggles. In the context of the original writing, the concept of "learning" is intimately tied to the idea of "experiencing." The focus is not so much on Jesus becoming aware of what suffering is, but Jesus actually putting into practice what He was called to do. He suffered.
