We all have one. That one person who has been there for you.

Whether it was during childhood, grade school, high school, college, or your first job, you found that person and she has been with you ever since. She has stood by your side when everyone else walked away. She never judged, doubted, or intentionally hurt you. And you love her. You love your person because she is irreplaceable. She holds a place in your heart that no one else ever will.

I met my person when I was four years old; it was the day my sister was born.

I didn’t know then what she would be to me now, but oh, how I am blessed. I am blessed in ways I cannot even begin to explain. She is my person and she will always be my person. And yes, I said my sister, not my husband.

Don’t get me wrong, I love my husband but husbands aren’t “persons”—they are spouses. They are our greatest loves. They are the fathers of our children. They make us whole. They have their purpose for us, but I don’t believe this is it.

Your person is someone different. It’s someone maybe you’ve known your entire life or maybe it’s just felt like that. The person who just gets you. It’s a relationship that requires no effort because you both know what you mean to one another. And while every relationship is different, here’s what mine is.

Mine is my best friend. My sister. The one person who has never given up on me, not even for a second, who has never judged me, hurt me, or done anything but be there for me. She’s made me a better person—a better sister, daughter, friend, wife, and mother. She’s my person. She knows what I’m thinking with one look, one word or even one GIF. She is the most generous, loving, kind, faithful, and loyal person I have ever met. She is someone I admire and respect. She’s the kind of person who is loved by all who meet her. She has a kindness you cannot fake. She has a faith that cannot be shaken. She is stronger than she knows. She is beyond beautiful inside and out.

Maybe your person is your sibling or the person you grew up from down the street. Maybe it’s the one you met your first day of kindergarten or freshman year biology. Maybe you met in the college dorm or your first job after graduation. Wherever you met, you know she is your person and you are hers. No drama, no jealousy, and very little arguing, if any. This person has your back, she doesn’t stab you in it. She loves you for the person you are. She accepts your flaws because you accept hers. You get each other. You talk at least once a day because that’s just what you do. You’ve seen each other at your best and worst and you’ve always been there for each other during those times. This person will forever be in your life.

I’m blessed I happened to grow up with my person. No one can ever truly know me like she does because she’s been there from the beginning.

I don’t remember what my life was like without her and I wouldn’t want to if I could. I am better because of her.

A while ago, I was struggling just as any other mother and wife does. My sister sent me Lauren Daigle’s song “Rescue”. She said this was her song to me. It, of course, brought me to tears. And that’s the amazing thing about having your person—she knows how to help you when you need it most with just the right thing.

No matter who, what, when, where, why, or how . . . she is your person and that will never, ever change.

Thank you for being who you are to me—I love you more than words could ever say.
