2 Corinthians 6:13 Now for a recompence in the same, (I speak as unto my children,) be ye also enlarged.

The Apostle Paul was a spiritual father to the church in Corinth. He was instrumental, used of God, to preach the gospel in Corinth, that resulted in God saving the souls that brought the church into existence. Therefore, years later, he speaks as a spiritual father unto his spiritual children that they would as children love their father as the father has loved them.

It is desirable that there should be a mutual good affection between ministers and their people, and this would greatly tend to their mutual comfort and advantage. [Matthew Henry]

2 Corinthians 6:12 Ye are not straitened in us, but ye are straitened in your own bowels.

The Corinthian Christians do not occupy a little or restricted portion of the Apostle Paul’s heart, he loved them dearly. He unequivocally tells them. The word “straitened” literally means confine, squeeze into a narrow tight place, restrict; figuratively in the passive, as having a cramped or narrow feeling be restricted, be severely limited. [Friberg]

MacDonald said well, “Any restriction in affections between the Corinthians and Paul is not in himself but in them. They might have limited love toward him, so that they were not sure whether they should receive him or not, but he was not at all limited in his love toward them. The lack of love was on their side, not Paul’s.”

The fact that he has come such a long way and endured many sufferings, he explained, is proof of his sincere love for them. He has to explain himself so that he may help them see that their affections toward him have been compromised.
