Hillsong United's "Oceans (Where Feet May Fail)" is the No. 1 song on Billboard Hot Christian Songs for the 2010s. The song was released on 23 August 2013 as the second and final single from their third studio album, Zion.
"Oceans," with lead vocals from the group's Taya Smith, spent a record 61 non-consecutive weeks at No. 1 on the Billboard Hot Christian Songs chart. In the year-end summaries, it was the chart's No. 1 song in 2014 and 2016, No. 2 in 2015, and No. 10 in 2017. The song spent a record 191 weeks on the list overall (more than twice its next-closest competitor).
"It's really a song about stepping into the unknown," explained Joel Houston, "about faith and raw trust in God."
In a 2016 interview with Billboard, Smith marveled at the song's success. "Are you serious? I really had no idea, I didn't," she said. "It was actually one of the first two songs that I sang after joining the group. What makes me happy about that is that so many people would hear the song and then maybe God can work in their own hearts."
