As mentioned before if we don't have manifestations of the supernatural as a Christian, then there is something wrong and we are likely just walking in the flesh.
In my previous post I covered a subject that this kind of branches off from, walking in the power of the spirit.
When we walk in the spirit, this is literally us connecting to this spiritual world through Christ by the power of the Holy Spirit, so we expect supernatural because it supersedes the natural..
I will paste the scriptures I included below
Joh 4:24 God is a Spirit: and they that worship him must worship him in spirit and in truth.
Phi 3:3 For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.
Joh 3:5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
Joh 3:6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
Eph 1:3 Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ.
Eph 2:6 And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:
Eph 3:10 To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God.
Eph 6:10 Finally, my brethren, be strong in the Lord, and in the power of his might.
Eph 6:11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.
Eph 6:12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
I will share some of my experiences in another post if anyone wants to hear?
