"I Can Only Imagine" is a song by Christian rock band MercyMe. Written and composed by lead singer Bart Millard, it was originally recorded for the band's 1999 independent album The Worship Project before being included on their 2001 major-label debut album Almost There. The song was the last to be written for The Worship Project; in writing it, Millard drew upon his thoughts about his father's death. Lyrically, it imagines what it would be like to be in front of God in heaven; it opens with just a piano before building to include guitar and drums.
