Jesus had thousands who gathered to see His miracles and teaching. There were hundreds who followed Him. Only 12 men were Apostles of Jesus. Even more narrow, 3 were part of His inner circle. But there was only 1 person who leaned on Jesus chest at the last dinner and was at the cross when Jesus gave His life. This was John. As the Holy Spirit leads John to recount specific parts of Jesus’s life and ministry, his target is our faith in Jesus as the means of our salvation.
