In a generation ruled by selfies, socialising and a culture of vanity, the things we post on social media tell us more than we would like to know about the true conditions of our hearts. While it's said that "out of the abundance of the heart the mouth speaks," (Luke 6:45) today the abundance of the heart also tweets as well.

Although we can't possibly judge people based on outward expressions, we get a clue of what truly lies in people's heart by looking at their own actions. Your profile picture, for instance, can speak volumes about who you are—and I'm not just talking about what fashion you carry on, what hobbies you like or who your significant other is. It goes much deeper than that.

The profile picture was meant to be a summary of who we are and what we want people to know about us. But it can often also reflect the things that we don't really say but we still speak loudly to others. Here are three of those things.

1. We All Strive for Affirmation

Within all of us is a need for affirmation and affection. It's just embedded in our nature. Some will look for it in the approval of others and, as a result, try to gather as many likes, follows and virtual friends as we possibly can, thinking that these things are valuable.

But our value does not come from who we are or what we try to add to ourselves. Thank God, because if it were we would be of very little meaningful value. Our value comes from Christ and the price He was willing to pay for us on the cross.

2. Flaws Are Better Covered Up Than Exposed

Some of the most overused filters on camera apps today are those that have the capacity to cover up pimples, wrinkles and even dimples. We don't like being exposed for who we really are, and that also applies to a spiritual level. We sometimes mask our imperfections and highlight our strengths.

But Proverbs 28:13 reminds us, "Whoever conceals his transgressions will not prosper, but he who confesses and forsakes them will obtain mercy."

There's nothing to be ashamed of because all has been redeemed by Christ.

3. Our Satisfaction Lies in Others

Because our approval can sometimes come from people, we tend to gain satisfaction from relationships. And that's not necessarily a bad thing because God did create us to value and build relationships. But we were never meant to gain satisfaction from it. We were meant to give into it.

The only source of satisfaction is God Himself. As Psalm 16:11 says, "You make known to me the path of life; in your presence there is fullness of joy; at your right hand are pleasures forevermore."
