Timothy was Pastor of the Christian “assembly” at Ephesus (1 Timothy 1:3). He was a young man. That is made clear by expressions in both letters to him and by references in the book of Acts. Paul’s references also leave us in no doubt that Timothy was very dear to him.
1 Timothy was written from Greece between 64-66 A.D.
The two epistles to Timothy are a “charge” from Paul to Timothy. We are told this at least ten times in the two letters.
Looking particularly into the first letter we see that it’s over-all subject is the local “church” or “assembly” of Christian believers and the pastor-in-charge.
The first 17 verses of chapter 1 give a preliminary explanation why the letter was being written, and end with a doxology.
The “charge” itself begins at the first verse of chapter 2, and then the letter breaks into two clear parts. Chapter 2 and 3 concern the assembly and its conduct. Chapters 4, 5 and 6 concern the minister and his conduct.
The theme of 1 Timothy is quite clear in 3:14 & 15
14. Although I hope to come to you soon, I am writing you these instructions so that,
15. If I am delayed, you will know how people ought to conduct themselves in God’s household, which is the church of the living God, the pillar and foundation of the truth.
Paul states here very simply that there is a standard of behavior for the church of God and that he is writing to Timothy to enable him to know it.
It is not enough to say to a child who is misbehaving, “behave yourself!” if the child does not know what is expected in the way of good behavior. He must be told first what good behavior is. 1 Timothy does this for the child of God in relation to the church of God.
