John means “eternal is gracious’” and James means “cloud.” Matthew 4:21 states that John and James were brothers.
James, son of Zebedee and his brother, John, “to them he gave the name Boanerges, which means sons of thunder,” Mark 3:17, Oxford New International Version (N.I.V.), Scofield Study Bible.
Peter turned and saw that the disciple who Jesus loved as following them. This was the same disciple that leaned back against Jesus at the supper and said, “Lord, who is going to betray you?” When Peter saw him, he asked, “Lord, what about him?” Jesus answered, “If I want him to remain alive until I return, what is that to you? You must follow me.” Because of this, the rumor spread among brothers that this disciple would not die. But Jesus did not say that he would not die; he only said, “If I want him to remain alive until I return, what is that to you,” John 21:20-23.
James and John have a mission in our time, soon to occur. Notice the two witnesses are slain and raised from the dead after three and a half days, plus go up to heaven in a cloud, Revelation 11:11-12. “The seventh and the last trump then occurs,” Revelation 11:15.
But the righteousness that is by faith says, “Do not say in your heart, who will ascend into heaven,” that is to bring Christ down, Romans 10:6.
“And in that day a great trumpet will sound. Those who were perishing in Assyia and those who were exiled in Egypt will come and worship the Lord on the holy mountain in Jerusalem,” Isaiah 27:13. “But the Jerusalem that is above is free, and she is our mother. Now you, brothers, life Isaac are children of promise,” Galations 4:26-28
