for the weapons of our warfare are not human weapons, ¹  but are made powerful by God ²  for tearing down strongholds. ³  We tear down arguments ⁴ 

For our reason for confidence ¹  is this: the testimony of our conscience, that with pure motives ²  and sincerity which are from God ³  – not by human wisdom ⁴  but by the grace of God – we conducted ourselves in the world, and all the more ⁵  toward you.
