How do I live ONLY IN THE SPIRIT?
Apparently, this will solve all my problems in life.
I was told: prayer and fasting is not the way.
So please, tell me.
Okay so I just have to believe ok i already believed Jesus died on cross for everyone's sins. Yes.
Now what?
I AM REALLY TRYING HERE MAN!!!!!!!!!!!!!!!!!!!!!!!!!!! COS I DON'T LIKE NOT BEING IN CONTROL OF MY FUTURE AND LEAVING THINGS IN THE OPEN!
I can appreciate the logical struggle you are expressing here.
In my mind, I separate two things.
I believed in Jesus and became born again, this started the new life.
Meanwhile, my old memories filled the space of the identity vaccuum because a baby doesn't know who they are.
So the first waypoint on that journey was seeing the difference between the New person I became when I was born again by the Holy Spirit, and the false identity created by the body using my memories. However, it might be different for you.
Living in the Spirit is living from the promptings of the new person you became when you were born again. The promptings of the Spiritual self are counter intuitive since it is like a rushing wind, and the old memory self is like the earth, impulsive and has instant gratification to advertise its existence.
You can "live in the Spirit only" when you have a firm identity of who this new creation is that came to being when you were born again by the Holy Spirit. Since each new creation has a unique purpose, the way to "discern" what your new creation is like may vary, since "the things of the spirit are hostile" to the instincts of the body.
Since it takes a long time to realize, I would recommend to continue in faith, faith is like breathing. Faith can also be translated as Trust when applied to relationships. If you have trust issues, focus on that. Sky walking can come later.
