Paul emphasises that he is not trying to restrict them or trap them. He has their own advantage in mind. He wants them to lead noble lives (compare Mark 15:43 - ‘ a noble councillor', same word, one well thought of and highly respected).

But he is well aware that many younger women are just as sexually motivated as men, and often need the tie of marriage, and what it involves, to motivate them in the right direction, and that is why in Timothy he enjoined that in general younger widows should remarry (1 Timothy 5:11; 1 Timothy 5:14). He recognised that he was dealing with the vast complexities of human nature (in its best sense) and gave his advice but left them to consider it accordingly. What he did want to bring home was that, contrary to much thought on the subject, remaining single was not wrong, and could be beneficial.
