1 Timothy is an epistle (letter) credited to the Apostle Paul. Paul would have to be consistent in order to be believed. And he is.
Ephesians 1:5 He predestined us for adoption as sons through Jesus Christ, according to the purpose of his will,
If you read all of 1 Timothy 1 for context you'll see this. What a perfect chapter.
Greeting
1Paul, an apostle of Christ Jesus by command of God our Savior and of Christ Jesus our hope,
2To Timothy, my true child in the faith:
Grace, mercy, and peace from God the Father and Christ Jesus our Lord.
Warning Against False Teachers
1 Timothy 1
Greeting
1Paul, an apostle of Christ Jesus by command of God our Savior and of Christ Jesus our hope,
2To Timothy, my true child in the faith:
Grace, mercy, and peace from God the Father and Christ Jesus our Lord.
3As I urged you when I was going to Macedonia, remain at Ephesus so that you may charge certain persons not to teach any different doctrine,
4nor to devote themselves to myths and endless genealogies, which promote speculations rather than the stewardship
a from God that is by faith.
5The aim of our charge is love that issues from a pure heart and a good conscience and a sincere faith.
6Certain persons, by swerving from these, have wandered away into vain discussion,
7desiring to be teachers of the law, without understanding either what they are saying or the things about which they make confident assertions.
8Now we know that the law is good, if one uses it lawfully,
9understanding this, that the law is not laid down for the just but for the lawless and disobedient, for the ungodly and sinners, for the unholy and profane, for those who strike their fathers and mothers, for murderers,
10the sexually immoral, men who practice homosexuality, enslavers,
b liars, perjurers, and whatever else is contrary to sound
c doctrine,
11in accordance with the gospel of the glory of the blessed God with which I have been entrusted.
Christ Jesus Came to Save Sinners
12I thank him who has given me strength, Christ Jesus our Lord, because he judged me faithful, appointing me to his service,
13though formerly I was a blasphemer, persecutor, and insolent opponent. But I received mercy because I had acted ignorantly in unbelief,
14and the grace of our Lord overflowed for me with the faith and love that are in Christ Jesus.
15The saying is trustworthy and deserving of full acceptance, that Christ Jesus came into the world to save sinners, of whom I am the foremost.
16But I received mercy for this reason, that in me, as the foremost, Jesus Christ might display his perfect patience as an example to those who were to believe in him for eternal life.
17To the King of the ages, immortal, invisible, the only God, be honor and glory forever and ever.
d Amen.
18This charge I entrust to you, Timothy, my child, in accordance with the prophecies previously made about you, that by them you may wage the good warfare,
19holding faith and a good conscience. By rejecting this, some have made shipwreck of their faith,
20among whom are Hymenaeus and Alexander, whom I have handed over to Satan that they may learn not to blaspheme.

Once can only reject what was given because as we glean from Paul's letter, those to whom he refers were already considered to hold faith and good conscience.
Acts 13:48 And when the Gentiles heard this, they began rejoicing and glorifying the word of the Lord,
and as many as were appointed to eternal life believed.
