Maybe it's a song that you heard in your favorite movie, or your prom or wedding. I guess this could be a good or bad thing depending on the memory, but I love that our minds are rigged that way.
For me, it is a combination of songs. A little over a month ago, some members of our Bible study went to Philadelphia for a four-day mission trip. Upon returning, I created a video of our experience, and the hardest part about it was picking out what music to put in the background. I couldn't pick one or two, but ended up using portions of four songs:
The Time is Now - Phil Wickham
Shadows - David Crowder Band
Far Away - Lecrae
City on Our Knees - Toby Mac
And now, every time I hear one of these songs, I am reminded of what I saw in Philadelphia.
And I am so thankful for that.
I became aware of God's presence amidst pain of joys of Philadelphia and I don't want to forget what that was. God can now use these songs to convict me of my comfort and inspire me to live a life that glorifies Him.
