Wherefore lay apart all filthiness and superfluity of naughtiness, and receive with meekness the engrafted word, which is able to save your souls.James 1:21 KJV
James, writing to Spirit-filled, born-again believers, told them that yes, that they needed to be saved. That’s right, they needed salvation in their souls.
When we are born-again, made new by the Holy Ghost, we are born-again in our spirits, not our souls. The Holy Spirit, God Himself, comes into our inner most being, further inside than our soul, and makes us new–we are ‘born again’. But, that does not make our souls or our bodies born-again in the least.
