The only thing that can divide them is the power of the Word. Before the Word divide the spirit and soul they were combined as one therefore making man a two fold being. Not the image nor likeness of God. So if spirit and soul must be divided that let us know that something have to be done to save our soul. So how do our soul becomes save you wonder.
First thing is to turn from wicked ways and get rid of it.
Then humble yourself with all meekness in receiving the Word through God's anointed mighty hand which are His Preachers. You have to learn how to take correction. Realize that you do not know the Word well enough to study on your own. I pray that you have been inspired through the Word of God to seek soul salvation. I pray that your soul have prospered and will continue to.
