Human spirit only speak in tongues? / WWY Q&A 53

We, as humans, know much about our body. We know a little less about our soul. We have some ideas regarding the human spirit. There are many people that 'speak in tongues'. But if we are engaging in SPIRITUAL warfare, wouldn't it be great if we could get our human spirit more involved than our human soul?

2Co 10:3 For though we walk in the flesh, we do not fight according to the flesh. 4 For the weapons we fight with are not fleshly but mighty in Elohim . . .
