I Believe In You embraces and proclaims the greatness and glory of God. On the title track, Engle launches into an unrelenting declaration of faith in God over a soaring orchestra and roaring guitars. The lyrics for songs like "Invincible," "Almighty God," "O Great God," and "King of Glory" also proclaim His incomparable goodness and insurmountable power while being backed by a full-throttle, modern-rock sound. The album is full of the kind of irresistable worship-anthems that inspire a sense of awe towards God while engaging crowds to join in the praise. Engle also offers a few pride-piercing ballads that cut right to the heart of an honest Chrisitan's daily struggle to live out his faith. Songs like "First Love" and "Capture Me Again" are sure to awaken and warm even the most worn-out and weariest souls.
