A Gentleman

What constitutes a gentleman? I suppose that everyone has their own definition. Here is mine:
A gentleman is one who, whether wearing blue jeans or creased slacks, conducts himself in a manner that is noticeably noble, gentle, and correct. One who treats the members of the opposite gender with respect and honor both physically and emotionally. He would not fiddle with a girl's heart, nor drop her like an old shirt if he has in error. A gentleman may be one who would willingly place a lady's safety and comfort above his own whether the girl be fair or plain, lean or plump, friendly or rude. For me personally, as a follower of Christ, a gentleman would also be described as humble and God-fearing; a man who sees Christ's cause above his or his country's, and the good of others higher than his own.
