Coming out of lukewarm, hypocritical, up and down, fake love Christianity, Jesse now does all he can to combat the broad way doctrines he was taught. Many partial truths overtime, produce a bigger picture that us untrue. Jesse has found victory in his battle over depression, bi-polar, rage, lust and weakness, by teaming up with soldiers like Artur who have taught him how to take the battle to the devil. No longer listening to those who through sneakiness, try to tone down his zeal, Jesse instead receives these verses deep in his heart.
Rev 3:9 As many as I love, I rebuke and chasten. Therefore be zealous and repent!
2 Tim 2:4 No one engaged in warfare entangles himself with the affairs of this life, that he may please him who enlisted him as a soldier.
