Passage
But concerning love of the brethren ye have no need that one write unto you: for ye yourselves are taught of God to love one another;
But concerning love of the brethren ye have no need that one write unto you: for ye yourselves are taught of God to love one another;
1 Thessalonians 4:7 For God called us not for uncleanness, but in sanctification.
1 Thessalonians 4:8 Therefore he that rejecteth, rejecteth not man, but God, who giveth his Holy Spirit unto you.
1 Thessalonians 4:9 But concerning love of the brethren ye have no need that one write unto you: for ye yourselves are taught of God to love one another;
1 Thessalonians 4:10 for indeed ye do it toward all the brethren that are in all Macedonia. But we exhort you, brethren, that ye abound more and more;
1 Thessalonians 4:11 and that ye study to be quiet, and to do your own business, and to work with your hands, even as we charged you;
The verse centers on "concerning", "love", "brethren", "need", "write", "yourselves", and "taught". It is saying that the verse draws attention to "concerning" and "love", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 8's "Therefore he that rejecteth rejecteth not man..." into verse 10's "for indeed ye do it toward all...", so "concerning" and "love" belong inside that flow. In 1 Thessalonians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "concerning" and "love" with trust shaped by these words, not by a vague optimism outside the passage.
