What biblical and theological principles can be applied to discern whether Jeremy Camp’s song "He Knows" is inspired by the Holy Spirit?

Jeremy Camp is a contemporary Christian artist known for music that deals with faith, suffering, and hope. His song "He Knows" contains the lyric: >All the bitter weary ways Endless striving day by day You barely have the strength to pray In the valley low And how hard your fight has been How deep the pain within Wounds that no one else has seen Hurts too much to show All the doubt you're standing in between And all the weight that brings you to your knees He knows He knows Every hurt and every sting He has walked the suffering This lyric suggests that Christ understands not just our physical suffering, but also our internal struggles and doubts. The song is often described as encouraging and biblically grounded. I’m seeking to understand what biblical and theological principles should be applied to evaluate whether such a song is inspired by the Holy Spirit. I’m not looking for personal opinions on musical style, but for scripturally grounded criteria such as alignment with biblical truth, spiritual fruit, and edification of the Church.
