Charles Spurgeon Commentary 2 Thessalonians 3:13-15

"But ye, brethren, be not weary in well-doing. And if any man obeyeth not our word by this epistle, note that man, that ye have no company with him, to the end that he may be ashamed. And [yet] count him not as an enemy, but admonish him as a brother." — 2 Thessalonians 3:13-15 (ASV)

This kind of Christian discipline ought to be carried out still, in reference not only to this one case of busybodies, but to all other cases. When a church grows large, there can be no efficient discipline from one man, or from all his officers with him.

There must be the discipline of the whole church towards itself, each Christian, according to his measure of grace, seeking the good of the whole; for while every man must bear his own burden, yet it is said, Bear ye one another's burdens, and so fulfill the law of Christ.

Look not every man upon his own things, but also upon the things of others. The careful desire to promote the Christian welfare of all our fellow members is a very different thing from being busybodies.

We must have equal desire not in any way to interfere where we should not.
