All this is to encourage Timothy. He is going to be given a view of God the Father and of Christ the Son who he is co-equal with the Father.
There are those cynics and liberal Bible teachers, who do not believe in the inspired inerrant word of God, and immediately they find fault with this verse. This is one of a number of similar verses which the cynics seize on, and they begin to criticize the Bible and say, ‘Look, here is an example of the Apostle Paul instructing Timothy in such a way that it's obvious that he thought that the Lord Jesus would appear soon in Timothy's lifetime. So the Apostle Paul could not have been completely inspired. He frequently says things that are mistaken. He doesn't tell him to keep the faith until the time of his death, he tells him to keep the faith until he sees the Lord, until the Lord appears.’ Well is that criticism justified? Of course it isn't. These people are such infants in the handling of the Scripture. They do not begin to understand the language of Scripture. Now we understand well enough – because the Bible is self-interpreting and it tells us to look at things in this way – that when the Apostle Paul speaks to Timothy, he not only speak to Timothy, he speaks to him and all his successors as teachers and members of the church of Jesus Christ. He is not only speaking to Timothy; he is speaking to the church as an institution; he is speaking to believers down the ages. Paul is not committing himself to the idea that he knows when the Lord is going to return. In fact, this is evident from what comes next in verse 15. The Apostle Paul is quite clear that no man knows the day or the hour of the coming of the Lord, that we cannot assume anything; that God must reveal that day and it cannot be known before then. The Apostle Paul has taught the same elsewhere, and the Lord Jesus Christ has taught in the parables that it may be that we have to wait a long time, perhaps many generations for the coming of the Lord. The Apostle Paul knows perfectly well that only God knows the day or the hour. This is what he means when he exhorts Timothy to keep the faith until the appearing of Christ. Yes, he is exhorting Timothy, but not implying that Christ will appear in his lifetime. Because even though we may die before the coming of Christ, the second coming of Christ, and even though we may be in the paradise of Christ for centuries before Christ comes again, everything we do on earth is to be done, every moment of our life is to be lived, in the light of the great triumph day of Christ.
