1:3 {2} As I besought thee to abide still at Ephesus, when I went into Macedonia, that thou mightest charge some that they teach no other doctrine,
(2) This whole epistle consists in admonitions, in which all the duties of a faithful pastor are plainly set out. And the first admonition is this, that no innovation is made either in the apostle's doctrine itself, or in the manner of teaching it.
1:3 As I besought thee to abide still at Ephesus. Paul, it is presumed, seeing on the occasion of his last visit the need of a trusty evangelist at Ephesus to counteract the errors which were arising, had left Timothy behind. He was not left there as a bishop, as has been sometimes claimed, for we find that a part of his business was to appoint bishops; but as the representative of the apostle, an evangelist. The office of Titus in Crete was similar.
That they teach no other doctrine. Than the gospel which they had been taught. Some of the errors which he was to correct are stated in 1Ti 1:4.
1:3 Charge some to teach no other doctrine - Than I have taught. Let them put nothing in the place of it, add nothing to it.
1:1-4 Jesus Christ is a Christian's hope; all our hopes of eternal life are built upon him; and Christ is in us the hope of glory. The apostle seems to have been the means of Timothy's conversion; who served with him in his ministry, as a dutiful son with a loving father. That which raises questions, is not for edifying; that which gives occasion for doubtful disputes, pulls down the church rather than builds it up. Godliness of heart and life can only be kept up and increased, by the exercise of faith in the truths and promises of God, through Jesus Christ.
