There was a desperate, restless aching in my soul to be loved, to find approval.
As I flipped through my feed, various streams of content flashed by:
Weddings & Romance. Accomplishments. Celebrations. Friendships.
Continuing to scroll, I felt the prick of discontentment steadily increasing.
Having abandoned the wisdom of God's Word, I foolishly disobeyed and compared my life to others (2 Corinthians 10:12). And where did that leave me? I was more miserable than before, more empty.
My identity was constructed on the superficial, shifting sands of social media.
That giant dune seemed safe and beautiful, even secure. Everyone flocked to it as a place to share, to thrive in friendships, to do life. But, once i found myself there, it was too tempting for me.
I kept going to it hoping that perhaps the next time, there would be a notification to boost my confidence or make me happy or to tell me: you really are beautiful or talented, just look at how many people say so.
My acceptance as a person hinged on the feedback - or lack thereof - from others.
No matter how many "likes" or compliments or comments or "friend requests I received, it was never, ever enough. My feet were planted on a foundation, deeply creviced, mere sand! It was tottering, tilting, entirely unable to support my weighty storm of soul desires and soul needs... an insufficient shelter that crumbled under the pressure to produce the love and acceptance I longed for.
Maybe I'm not alone? Perhaps you have been moved, tears welling in your own eyes as you think back over your life. have you built on shifting sand too? Well, friend, listen close. Here is where hope breaks through the brightest:
It's not too late to build our lives on the Rock.
Jesus is a shelter for those who call upon His name. We can run to Him in the storms and find safety (Proverbs 18:10).
Our secret fears and struggles are open before Him. Nothing, nothing is hidden from His holy sight! He knows the very depths of our depravity, our sins, our shame. And He bore all of these on the cross, willingly. We can embrace this truth in the humble quiet, on-our-knees kind of awe. The only thing that can and will truly, completely satisfy our soul is Christ. His everlasting love - from the foundation of the world - was poured out (John 17:23-24).
"Jesus Christ is in every way sufficient to the vast desires of the soul." - John Flavel 
If the very One who framed the world with His Word, who caused the starry expanse to come into being with His breath can have mercy upon us, fulfilling the law completely, and stand willing to forgive us, we have nothing left to fear (Psalm 33:6, John 1:29, 8:39). This knowledge fills up, brims to overflowing.
I lost sight of this in my wandering. I took my eyes off of Him, off of His costly loveliness and love towards me.
So, take a lesson from my scrapes and bruises received after the shifting sands crashed down. Glean from what I learned after my foolishness. Don't settle for superficial, fake love. Begin building your life upon the Rock. Drink deeply of the real thing!
On Christ, the solid Rock, I stand;
All other ground is sinking sand,
All other ground is sinking sand.
