From John 21's scene on the beach, between Jesus and Peter:
Then Jesus said to him, “You must follow me.”
Then Peter turned round and noticed the disciple whom Jesus loved following behind them. (He was the one who had his head on Jesus’ shoulder at supper and had asked, “Lord, who is the one who is going to betray you?”) So he said, “Yes, Lord, but what about him?”
“If it is my wish,” returned Jesus, “for him to stay until I come, is that your business, Peter? You must follow me.”

"There is no more subtle temptation than to wait with what God calls us to do till we are first informed what others are to do, or what God is to do with the rest of the world. We may safely leave to Him who is ruler of all, the All-wise, what will come of obedience to His commands. To every question, And what shall this man do? Christ's answer is, What is that to thee? Follow thou Me. If we are disciples of Christ, each one of us must seek to have as much of His Spirit as can be. If we are to be led by Him in the new and living way, to live with Him in the Holiest of All, we must, like Him, live here as pilgrims and strangers."
