1 Thessalonians 4:10

Indeed ye do it. This was another reason for Paul’s not needing to write more concerning brotherly love. The Thessalonians had already shown their love toward the believers in northern Greece, and Paul had commended them at the beginning of the epistle for their “labour of love” (see on ch. 1:3). He does not explain what form their brotherly love took, but it was doubtless Christian hospitality toward fellow Macedonians. He now uses this proved trait as a basis for appeal in respect to purity of life. Having demonstrated their love on such a large scale, surely they will practice it in their day-by-day relationships with their brethren in the church.

We beseech. Rather, “we exhort” (cf. on v. 1).

Increase more and more. Compare the phrase “abound more and more” (v. 1). The love that the Thessalonians displayed is not yet perfected. He entreats them to strive for still higher attainments. The Christian path is one of continual progress. It is only when we love one another fully that God’s love is perfected in us (1 John 4:12, 20, 21).
