The quote reflects a moment of personal transformation where the speaker chooses to embrace faith, potentially as a means to navigate challenges in a marriage. The decision to let God into his heart suggests a search for deeper meaning or solace amidst turmoil. It's indicative of a struggle between spiritual conviction and personal strife, highlighting the complexity of seeking solace in belief during difficult times.

Furthermore, the phrasing implies a somewhat ironic or conflicted approach to faith, as the speaker hopes to wield this newfound belief as a "vicious weapon" in his marital conflicts. This reveals a juxtaposition between the ideals of faith, which typically promote love and understanding, and the more combative reality of human relationships, particularly within marriage. The choice to utilize faith in such a manner showcases the multifaceted nature of belief in personal struggles.
