I stir up faith in God by placing myself around the things of God and meditating on His ways.
I stir up fear, demonic faith, by placing myself around things that are not of God and not meditating on His ways.
The spiritual person places their focus on spiritual things. The carnal person carnal things.
In Christ, my walk in God, pleasing or not pleasing to God, will be the direct result of what I placed my affections upon and devoted my thoughts too.
In Christ, my heart or understanding is a garden before God. I choose what I want to grow there. When I see something contrary to God there. I can go to God and ask Him to change it.
Those who live according to the flesh have a mind that is set on carnal things. And that kind of mind will never please God because its not subject to God, and it's end is death.
The spiritual mind is set on spiritual things. And that kind of mind is subject to God, it walks in life and peace, and it's end is life.
5 For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit, the things of the Spirit. 6 For to be carnally minded is death, but to be spiritually minded is life and peace. 7 Because the carnal mind is enmity against God; for it is not subject to the law of God, nor indeed can be. 8 So then, those who are in the flesh cannot please God.
9 But you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. Now if anyone does not have the Spirit of Christ, he is not His. 10 And if Christ is in you, the body is dead because of sin, but the Spirit is life because of righteousness. 11 But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ from the dead will also give life to your mortal bodies through His Spirit who dwells in you.
Sonship Through the Spirit
12 Therefore, brethren, we are debtors—not to the flesh, to live according to the flesh. 13 For if you live according to the flesh you will die; but if by the Spirit you put to death the deeds of the body, you will live.
