well, allow me to make our understanding identical.
i assumed faith is faith to JESUS correct ? why it's important ? because faith is instrument. faith is like a car. you can choose to drive your car, your you can choose to take a bus. faith to JESUS meaning we choose to trust in JESUS. But other religion has different faith right ? they choose to believe in something else. So here i believe is : faith to JESUS. but of course for simply writings, faith
.
to make a deeper understanding, take a look at salesman shoe here:
http://betterlifecoachingblog.com/2010/05/21/shoe-salesmen-in-africa-a-story-about-optimism/
here is my comment: the salesman has faith that he can sell, because nobody wearing shoes. the other salesman (the fear one) he choose to fear, because nobody wearing shoes.
same fact right ? nobody wearing shoes
back to your question / comments, it is essentially correct that not having faith causes the heart to have fear. to make understanding better, compare faith as water, fear as no water (aka empty). A glass is either filled with water or empty. We can decide to have 1/4 filled, half or anything we want.
faith is not only believe in JESUS, but to apply it further by receiving it. The essence is found in Mark 11:24
Therefore I tell you, whatever you ask for in prayer,
believe that you have received it, and it will be yours.
to conclude: people without the ability to believe that what they pray has been received, will surely has lack of faith. Bible knowledge probably GPA = 4.0 but faith GPA ?
... those with faith GPA = 0.5 (scale of 4), his heart will naturally swing back to fear mode and more fear will attract fear.
How to relate fear = deceitful heart ? you will accuse your heart is deceitful because whatever you do is wrong, and everything your inner man says leads to more trouble correct ?
Sure up to this point nothing flow out of his heart, only doctrine and perhaps may i add: law ? the law that only bring death.
I know i explain a lot, and unstructured. let me know if you don't understand.
