"Promise Keeper" is one of my favorite songs because it holds truths that I deeply believe and live by: our God is a promise keeper and His word never fails. I haven’t always been so confident of this, and those were the seasons when I had to dig deep to figure out what I believed.

My life alone, the journey of the record, is truly a picture of God keeping His promises. I felt like God told me when I was a young girl that I would be a singer and make albums. But, just like life, there were a lot of twists and turns, and things didn’t go as I had planned.

Twice, I attempted to pursue a career as a recording artist. God shut these attempts down and redirected my steps. Both times were filled with disappointment, but the fear of being disobedient was always stronger. I did what God asked and, in those moments of obedience, I experienced the goodness of God in ways I didn’t expect: left turns that felt like missteps constantly turned into places of healing, freedom, restoration, revelation, and confidence.
