"A woman with the courage to step out into the unknown, risking temporary loneliness for a shot at lasting joy, is more than a "single". She's singular. Instead of defining herself by what she lacks--a relationship with a man--she defines herself with what she has: a relationship with God.
...a singular woman bases her actions on how they will enable her to be the person she believes God wants her to be. If she longs to be married, she trusts that God has a plan for her and that a husband is part of that plan. Moreover, she trusts that God will provide all that He has planned for her if she follows His will for her life, making the best use of the gifts she has been given. She'll still enjoy parties and meeting people--but as ends in and of themselves, not just as a means of finding a man.
Perhaps the most noticeable difference between a single woman and a singular woman is one of gratitude... The singular woman not only expresses more gratitude..., but she also expresses it for different things. She's not just grateful for things she receives but for the opportunities to give. She knows in her heart the spirit of G. K. Chesterton's words: "The world will never starve for want of wonders; but only for want of wonder."
To be singular is to embark on a wide excursion of discovery. No more is your identity limited to qualities that can be defined by the checkoff boxes in an online personal ad. It's no longer what you do--but who you are. Prayerfully, you strive to develop inner qualities--like empathy, patience, humility and faith in spite of hardship.
...I can tell you from experience that the more you develop a singular identity, the more confident you will become around men and in every area of your life, because you will be comfortable in your own skin."
