For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart.
As a believer we are told in Galatians 5:16 if we live a life governed by our spirit man within, we will not walk in the ways of the flesh, which the ways of the flesh lead us out of God’s will. When led by our spirit man we will always follow God’s ways, for the Holy Spirit bears witness with our spirit. We are a spirit being, we have a soul made up of our mind, will, and emotions, and we live in a body. Whenever we are led by our soul and not our spirit man, we are functioning under the old Adamic nature.
For many they may not know if their soul is leading them or if it is their spirit man. Many believers may think they are being led by their spirit, but how can we know whether our spirit man or our soul is leading us? Most will refer to how they “feel”, which is often their soul and not their spirit. Well we have the ability to know whether it is our spirit man or our soul we are following. Hebrews 4:12 tells us how. God’s Word is the very thing that separates what is from our spirit man and what is from our soul, for His Word not only divides the two, but shows us the very thoughts that come from our heart.
Whenever we are making decisions that go against God’s Word we are following our soul, not our spirit man. Your new born again spirit will never lead you to do things opposed to God’s Word, for the Holy Spirit who lives in your spirit will always lead you in line with God’s Word. So when you want to know if you are following your soul (old Adamic nature), or your spirit man, just look to God’s Word. When your choices line up with God’s Word, you are being led by your spirit man.
