First of all it's a christian band that sings about God. For example. Songd like forever in your hands, not alone, and a song for the hopless. It doesn't take a genious to figure out who's calling he needs and it's jesus's sacrifice. The burning in his heart is the temptation of sin. Like he sais "i steel my nerves for temptations at hand. I hear this calling still you don't seem so far at all! Means I hear him calling and he isn't far at all. Exactly as it sais lol. I'll note the past and spare the pain (he knows what he has done and he asks to spare the pain). Now with the onset, my flesh is weakening. (it means with the spirit inside and the power of god he will over come the cravings for the flesh) and never forget these choices were made by me. (he knows it's his fault and he hears jesus and knows he's not far at all). My strength has been tested (by god). Still I belive this calling (of god) will see me through (he's be granted eternal lie! The song is made from verses such as john 3: 16 lol. Not trying to be a jerk but not every heavy metal band is about crap a lot of these guys feel it with their hearts and play the sufferings christ went through by showing evberyone through song lol.
