What do you mean by weapons? Excluding God from any area of our lives is a weapon alienating us from God. Disbelief of existence of God, "I have nothing to do with God", "I don't need God", I have no reason to listen to God" kind of attitudes are weapons we unwittingly use to resist against God's authority. But if we accept God's authority over all his created beings including ourselves, embrace his grace and forgiveness extended to us in the blood of Jesus Christ, and totally submit ourselves to his lordship, then we are in peace with God because it is a real surrender.
