The song has a soothing and slow rhythm that makes you want to listen to it over and over again. And a piano being the only instrument used makes her voice more pronounced & it sonority better appreciated.
The first verse is about God’s amazing love & grace for her but how she didn’t understand it, thereby taking it for granted.
The second verse is about how she’s asking God to help her understand His love & grace for her.
The chorus talks about how she constantly lets go of God & tries to go her own way but ends up hurting herself. But now she’s back asking for God’s help. Through it all though, God never let her go & never stopped loving her. Its a typical representation of the prodigal son’s story in the Bible.
