The same spirit of faith. What does that mean, to have a spirit of faith? 1 Thessalonians 5:23 says:
Now may the God of peace Himself sanctify you completely; and may your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ. We see here three distinct parts of man. The spirit, the soul, and the body. Look at Hebrews 4:12:
12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
See how the scriptures divide the spirit and the soul? The word of God divides them so they cannot be the same. Do a deeper research into this area and you will find that the mind or soul can conflict with the word of God, causing the spirit or heart to err. Paul teaches us to be renewed in the spirit of our minds. That sounds like a paradox but the word has to enter into your mind or your “soul,”and if it is not cast out, it will fill the heart or your “spirit”. The life forces that change things come from the heart or the spirit. That will help your understanding concerning when you say certain things, they almost always come to past, but when you attempt to put God’s word into speech, it seems the opposite takes place, because that word is not flowing forth from your heart or spirit.
2 Corinthians 4:13
