Here is one professional charged with the sheep:
When therefore they had dined, Jesus saith to Simon Peter: Simon son of John, lovest thou me more than these? He saith to him: Yea, Lord, thou knowest that I love thee. He saith to him: Feed my lambs. He saith to him again: Simon, son of John, lovest thou me? He saith to him: Yea, Lord, thou knowest that I love thee. He saith to him: Feed my lambs. He said to him the third time: Simon, son of John, lovest thou me? Peter was grieved, because he had said to him the third time: Lovest thou me? And he said to him: Lord, thou knowest all things: thou knowest that I love thee. He said to him: Feed my sheep. (John 21:15-17)
And this is what that professional thought of finding salvation "personally".
Understanding this first, that no prophecy of scripture is made by private interpretation. (2 Peter 1:20)
Here is what the Lord said to Peter when he was caught fishing rather than being about his Father's business:
Jhn 21:21 "Peter seeing him saith to Jesus, Lord, and what [shall] this man [do]? Jesus saith unto him, If I will that he tarry till I come, what [is that] to thee? follow thou me."
He told Peter that it was none of his business what the Lord had in store for John. His business was to follow Christ. After his hypocrisy in Galatia and his brief statement at the Jerusalem Council we don't hear anything about Peter except as an illustration in the first letter to Corinth and his two letters.
Prophecy is not of private interpretation, that is why the Holy Spirit came and leads each believer into all truth. It's not what I think but what the scripture says. "Believe on the Lord Jesus Christ and you will be saved."
