"Water Deep" is a song recorded by American singer-songwriter and record producer Marian Renta released as a single on March 13, 2026. The single's release was accompanied by the song's music video which features Renta singing in a church while the past version of herself runs in the woods from an unseen force. "Water Deep" is a downtempo, acoustic Christian Gospel anthem driven by piano, drums, and vocals, including a full choir. Written, composed, and arranged by Renta, the song spreads the Gospel message, warning unbelievers of the imminent return of Jesus Christ and urging believers to be baptized going down in the 'water deep'. The song conveys themes of faith, endurance, biblical truth, the atonement of sin through Christ, and the rapture. Renta has stated that the song is her means of carrying out the Great Commission of spreading the Gospel message to edify believers and plant seeds in unbelievers. "Water Deep" is an acoustic piano-and-vocals Gospel song that features soulful and emotional vocals by Renta that soar gallantly over a large church choir, making use of grand and intricate vocal arrangements. "Water Deep" was produced, mixed, and mastered by Renta at her recording studio MixFire Studios in New York.
