Before a person can believe in Christ !
Before a person can believe in Christ unto salvation, a new creature he or she must be ! By being a New Creation, we are given by the Spirit both light and Life, by which we receive New Spiritual faculties appropriate to receive Spiritual and Divine Truths. That's why Jesus said that he with good ground received the word and understandeth it Matt 13:23
23 But he that received seed into the good ground is he that heareth the word,
and understandeth it; which also beareth fruit, and bringeth forth, some an hundredfold, some sixty, some thirty.
That's because the New Spiritual faculties of the New Creation.
It is then also we are given spiritual eyes to see Jesus Jn 6:40
40 And this is the will of him that sent me, that every one
which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
Heb 2:9
9
But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man.
But we see Jesus,.... Not with bodily eyes, but with the eyes of the mind, and understanding; that he is Jesus, as the Syriac version reads; and that he is designed in the above words; and that he has all things made subject unto him; and that he was humbled, and now exalted, as follows: JG
It is then we receive spiritual ears to hear the glad tidings of the Gospel of our Salvation Eph 1:13 We need to be of God to hear God's words as such is the Gospel Jn 8:47
47
He that is of God heareth God's words: ye therefore hear them not, because ye are not of God.
We cannot be of God without having God's Life in Us by His Spirit ! We are given a spiritual palate to begin to hunger and thirst for the things of God Matt 5:6
Blessed are they which
do hunger and thirst after righteousness: for they shall be filled.
Yes, even the word of righteousness Heb 5:13
For every one that useth milk is unskilful in
the word of righteousness: for he is a babe.
Without these things from a New Life, and are remaining natural and in the flesh, then we are war and enmity with Christ and the hings of God Rom 8:7-8
7 Because
the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
8 So then
they that are in the flesh cannot please God.
1 Cor 2:14
14 But
the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him:
neither can he know them, because they are spiritually discerned.
14 But the natural, nonspiritual man does not accept or welcome or admit into his heart the gifts and teachings and revelations of the Spirit of God, for they are folly (meaningless nonsense) to him; and he is incapable of knowing them [of progressively recognizing, understanding, and becoming better acquainted with them] because they are spiritually discerned and estimated and appreciated.AMP 4
