I've been thinking about the question for a while and my short answer is: YES!!!
Now before I elaborate on that answer, let me explain what I'm referring to as your online presence.(OP)
Your OP is essentially who you are on the internet. Your profiles and posts on Facebook and Twitter, your boards and pins on Pinterest, your photos on Instagram, wherever you are online is your presence.
So does it really matter how you/I portray ourselves online? Again, yes!
I'm a Christian, which means to be Christ like, and in doing that, I try to emulate Christ in every part of my life. Even when I think others won't see. That being said, if I'm a Christian, I'm a Christian all the time, not just when I'm around other Christians.
The way I choose to use my OP is as a branch of myself; another way to get to know me. So whatever I do online reflects who I am in person.
That being said, I'm not trying to be pretentious or act holier-than-thou. I just choose to act according to my beliefs in real life.
While I'm not perfect, in real life or otherwise, I also try to live my life as a witness. For me, most times my testimony is told without speaking: I'm always wearing a skirt. Often people will see me wearing a skirt and start a conversation with me and that's how I tell them what I believe.
I think the internet can work the same way. I've met quite a few Message believers because we noticed each others bios or post or pins reflected our common beliefs.
I don't know who sees my OP but I hope that whoever does will see a testimony of Christ in my life.
Of course, you can always choose to keep your profiles as secrets, or only certain people who "understand" will see what you've been up to online. But God sees everything, even when others may not.
Now listen, church, I love you. And I want you to listen to me now. As Brother McCullough used to say, I'm going to say something. Always put the Lord before you, and don't you do nothing that you wouldn't do in His Presence, because He's watching over you. See? The Lord is encamped about those who fear Him. He don't… He just stays right near you. And He knows everything you're doing, and you must recognize that. When you start to tell a lie, don't do it, remember, God is listening at you. If you start to do a little cheat, don't you do it, God's looking at you. If you start to take His Name in vain, don't do it, God's listening at you. Start to smoke a cigarette, He's watching you. See? His… We used to sing a song, "All along on the road to the soul's true abode, there's an eye watching you; every step that you take, this great eye is awake, there's an eye watching you." Remember, do like David, put the Lord always before your face. Then your heart will rejoice and your flesh shall rest in hope, for He promised it. Yes, sir. He knew that he would raise up because God had promised it. All right.
