Charles Spurgeon Commentary 1 Timothy 1:5-7

"But the end of the charge is love out of a pure heart and a good conscience and faith unfeigned: from which things some having swerved have turned aside unto vain talking; desiring to be teachers of the law, though they understand neither what they say, nor whereof they confidently affirm." — 1 Timothy 1:5-7 (ASV)

There were some who put the law into its wrong place. They made it a way of salvation, which it never was meant to be, and never can be. It is a way of conviction. It is an instrument of humbling. It shows us the evil of sin; but it never takes sin away.
