13 You were well aware that the reason I ended up preaching to you was that I was physically broken, and so, prevented from continuing my journey, I was forced to stop with you. That is how I came to preach to you. 14 And don't you remember that even though taking in a sick guest was most troublesome for you, you chose to treat me as well as you would have treated an angel of God - as well as you would have treated Jesus himself if he had visited you? 15 What has happened to the satisfaction you felt at that time? There were some of you then who, if possible, would have given your very eyes to me - that is how deeply you cared!
Matthew Henry's Commentary on Galatians 4:13-15
Commentary on Galatians 4:12-18
(Read Galatians 4:12-18)
The apostle desires that they would be of one mind with him respecting the law of Moses, as well as united with him in love. In reproving others, we should take care to convince them that our reproofs are from sincere regard to the honour of God and religion and their welfare. The apostle reminds the Galatians of the difficulty under which he laboured when he first came among them. But he notices, that he was a welcome messenger to them. Yet how very uncertain are the favour and respect of men! Let us labour to be accepted of God. You once thought yourselves happy in receiving the gospel; have you now reason to think otherwise? Christians must not forbear speaking the truth, for fear of offending others. The false teachers who drew the Galatians from the truth of the gospel were designing men. They pretended affection, but they were not sincere and upright. An excellent rule is given. It is good to be zealous always in a good thing; not for a time only, or now and then, but always. Happy would it be for the church of Christ, if this zeal was better maintained.
