"Living In The Moment"
I'll tell you why I love it and it's because to my mind this song is all about trusting God.
Letting myself off the hook for things I've done: Romans 8:1
I let my past go past: Philippians 3:13
I will not waste my days...worry[ing] about all those things that will not happen to me: Philippians 4:6-7
So I just let go of what I know I don't know: Matthew 6:32-33
The idea of the entire song as a whole: Romans 12:2 and Ephesians 4:23
It's about paying attention to our thoughts and not letting them rule us. We can have all sorts of thoughts run through our heads on a daily basis that are unhealthy for us. We have to choose to let the good ones stick and not give the unhealthy ones room to settle. We can't stop thoughts from popping through our brains, we can only choose to measure them against what we know to be true and to discard thoughts if they prove to be false. The truth is so much greater than the lies we can let ourselves believe.
