Galatians 1:6-7
"I am astonished that you are so quickly deserting the one who called you to live in the grace of Christ and are turning to a different gospel, which is really no gospel at all; but there are some who trouble you and want to pervert the gospel of Christ"
Here, the apostle endeavors to impress upon these Galatians a sense of their guilt in forsaking the gospel way of justification; and yet at the same time, he tempers his reproof with mildness and tenderness towards them.
He represents them as being drawn away (to a different gospel) rather than coming to it of their own accord. Though this does not excuse them, it allows for grace to work, as it can be viewed as not entirely of their own volition.
This teaches us that, in reproving others, as we should be faithful, gentle, and endeavor to restore others in the spirit of meekness.
The Truth
“Brethren, if a man is overtaken in ant trespass, you who are spiritual restore such a one in a spirit of gentleness, considering yourself lest you also be tempted.” (Galatians 6:1)
