1:5 {4} Now the end of the {c} commandment is {d} charity out of a pure heart, and [of] a good conscience, and [of] faith unfeigned:
(4) The second admonition is, that the right use and practice of the doctrine must be joined with the doctrine. And that consists in pure charity, and a good conscience, and true faith.
(c) Of the Law.
(d) There is neither love without a good conscience, nor a good conscience without faith, nor faith without the word of God.
1:5 The end of the commandment is charity. The purpose of the charge (Revised Version) entrusted to you is love. See 1Ti 1:3. You must show these teachers that instead of teaching foolish fables they must inculcate love. The three things essential to a pure and holy love are: (1) A pure heart; (2) a good conscience; and (3) sincere faith.
1:5 Whereas the end of the commandment - of the whole Christian institution. Is love - And this was particularly the end of the commandment which Timotheus was to enforce at Ephesus, 1Tim 1:3,18. The foundation is faith; the end, love. But this can only subsist in an heart purified by faith, and is always attended with a good conscience.
1:5-11 Whatever tends to weaken love to God, or love to the brethren, tends to defeat the end of the commandment. The design of the gospel is answered, when sinners, through repentance towards God and faith in Jesus Christ, are brought to exercise Christian love. And as believers were righteous persons in God's appointed way, the law was not against them. But unless we are made righteous by faith in Christ, really repenting and forsaking sin, we are yet under the curse of the law, even according to the gospel of the blessed God, and are unfit to share the holy happiness of heaven.
