Energetic, inspirational, and built on gleaming hooks, Relentless is Christian pop at its best. Four songs were released as singles, but truthfully, every track sounds like it should have been a bit hit—from the surging, determined “I Will Not Be Moved” to the soaring sing-along “Let Go.” Lyrically, Grant focuses on God’s strength in the midst of human weakness: “Perfect People” looks to the Lord’s holiness as the balm for human fracture, and the modern worship classic “In Christ Alone” makes for the perfectly devotional closer.
