"who, in the days of His flesh, when He had offered up prayers and supplications, with vehement cries and tears to Him WHO WAS ABLE TO SAVE HIM FROM DEATH, and was heard because of His godly fear....." (Hebrews 5:7)
It could be said that what Jesus prayed for, asking humbly of the Father with vehement cries, and was heard because of His godly fear, was to be saved from spiritual death. Surely spiritual death surrounded Him, most ardently among many of the Hebrews. He wanted no part of that! Most importantly, He knew what His calling was. If Jesus' cries to His Father had been to be saved from physical death, and the Father heard Him because of His godly fear, then along the way the Father changed His mind (which we know doesn't happen), for we know Jesus was called to physically die for Israel, and all men. No, Jesus humbly asked for the Father's empowerment to save Him from that which would destroy Him and doom mankind.
Jesus informed Paul, in a trial of the flesh which prompted Paul to plead with the Lord three times that "it" might depart from him: "My grace is sufficient for you, for My strength is made perfect in weakness." (2 Corinthians 12:7-10) What empowered Jesus to complete His calling from the Father was His steadfast approach to Him (seeking to find), understanding that He could not finish without the Father and His Holy Spirit, He vehemently cried out to Him Who was able to save Him from spiritual death. Those Satanic temptations (Matthew 4:1-10), if He had succumbed, would have resulted in spiritual death for the Son of Man; that is why it came. But, our Lord was singularly focused on His Sonship from God!
His grace is sufficient for us! Each step toward it makes the Way, the Truth, the Life clearer and empowers those to rejoice in it with thanksgiving.
