From a blogpost I shared over a year and a half ago…
Now the end of the commandment is charity out of a pure heart, and of a good conscience, and of faith unfeigned: 6 From which some having swerved have turned aside unto vain jangling; 7 Desiring to be teachers of the law; understanding neither what they say, nor whereof they affirm (I Timothy 1:5-7 KJV).
These false teachers claimed to be professional interpreters of the Law, but really their theological teaching was only useless talk. They had no understanding of what they claimed or affirmed, as they were not men of Faith in Christ Alone.
And I thank Christ Jesus our Lord, who hath enabled me, for that he counted me faithful, putting me into the ministry; 13 Who was before a blasphemer, and a persecutor, and injurious: but I obtained mercy, because I did it ignorantly in unbelief. 14 And the grace of our Lord was exceeding abundant with faith and love which is in Christ Jesus (I Timothy 1:12-14 KJV).
The LORD Jesus called and enabled Paul to be faithfully committed to the Gospel that it might not be compromised. Before his encounter with Jesus on the road to Damascus, Paul had been the chief of sinners, but when he was Saved, he obtained Mercy that he might not walk in ignorant unbelief any longer. The Grace of God produced in Paul the Faith and Love which is in Jesus Christ.
This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief. 16 Howbeit for this cause I obtained mercy, that in me first Jesus Christ might shew forth all longsuffering, for a pattern to them which should hereafter believe on him to life everlasting. 17 Now unto the King eternal, immortal, invisible, the only wise God, be honor and glory for ever and ever. Amen (I Timothy 1:15-17 KJV).
Paul exhorts Timothy that the Gospel of Christ dying to save sinners is worthy of being accepted by the whole world. His offense against God had been so great and his sin of guilt so overwhelming that he numbered himself as the top sinner of all time. And if the LORD would Save him, He will do it for anyone.
