Sometimes you find a thing without looking for it. You stumble upon it, and that's still "finding" (Gen 37:15). Sometimes you look everywhere for a thing and never find it (Gen 2:20), yet God provides. Sometimes there's a gift of celibacy (?). (Sometimes I think Paul uses sarcasm, but maybe I am of little faith.)
Certainly God has gifted wives to men, and sometimes He has commanded a man to take a specific woman. I am not sure it is recorded that He has ever directly commanded men to seek wives in general for themselves, but I do think we can infer such an order from His command to fill the earth and subdue it. I think we see a pattern of the men of old exhibiting an understanding that they have an obligation to take women by any means necessary to fulfill this command. That sense of obligation is further supported when we see the men of old exhibiting an understanding that it was their responsibility (part and participle of God's authority delegated to them) to seek the first wife for their sons before their sons reached the age of accountability. I suppose we are assuming that the Proverbs reference is speaking of a man finding a wife for himself and not for his son. In any case, all throughout the Bible there seems to be the solemn understanding of an urgency for every woman to be wed and to make babies, and that men are the ones responsible for this fulfillment of the purpose of women.
I think we are given two examples for how to secure a bride, and we may follow either one in order to keep our earthly image patterned after the spiritual it is ordained to represent. The first is forced, which is shown us through God's choosing and taking of Israel without her choice. The second is offered, which is shown us through the God's Son standing at the door of each of us and knocking, and He will only enter and sup with those who choose to open to Him. The first pattern seems to be a highly specific bride of His choosing (who turned out to be stubborn and proud), and the second pattern seems to be any bride, but specifically only one who humbles herself and acknowledges her need. Both of these patterns seem to me to involve actively seeking.
I think men raised under the generic circumstances of the Western world are conditioned to be clueless, frightened, and/or ashamed to rise up and grasp this part of our duty (edit: doing it as a duty...many will pursure women, but as a natural instinct and not understanding why, doing it just for fun or because everyone else is). And I include myself in that bunch. But, also I think those are wise who cautioned to be careful about which women you take into your kingdom. These are dangerous times, and we are no good to anybody if we allow a Jezebel to destroy us.
