Exactly Tim! We are spiritually dead before being born again through Christ's Spirit. We have only a natural spirit giving our body physical life. We who WERE DEAD spiritually in trespasses and sins had to be made to live spiritually, so that we could both know and enter the Kingdom of God spiritually. For the Kingdom of God is within you! How can our spirit be spiritually dead when we are physically alive? We are without knowledge of Christ who came to give us life. Being without knowledge of the Savior the spirit giving our body physical life in us, has no desire to turn to Christ repenting of our sins when we hear preaching of the Gospel in the power of the Holy Spirit.
This conversion from spiritual death to spiritual life that is found only in Christ is having part in His resurrection life, for He is the first resurrection of the dead who shall die no more.
It is not either air or the Holy Spirit Tim! It is the Holy Spirit entering into our spirit that we shall have eternal/never ending spiritual life through Him. Because being
in us means He shall never leave us, even after our spirit giving our body life returns to God in heaven. If having only a spirit giving our body natural minds, thoughts, will and emotions, why would Paul write
we were dead in trespasses and sins?
Reading the mind of Solomon through what he wrote and concluding he had not knowledge of God that could only come by the Spirit of God WITH him, shows you might lack knowledge of the power of God given man through His Spirit???
Ecclesiastes 2:26 (KJV) For God giveth to a man that is good in his sight wisdom, and knowledge, and
but to the sinner he giveth travail, to gather and to heap up, that he may give to
him that is good before God. This also
is vanity and vexation of spirit.
Ecclesiastes 3:14 (KJV) I know that, whatsoever God doeth, it shall be for ever: nothing can be put to it, nor any thing taken from it:
and God doeth it, that men should fear before him.
The last verse recorded in Ecclesiastes sums up well the FACT that Solomon was NOT spiritually dead as you assume. What Solomon understood and you appear not to, is while living in this age with both a spirit that gives physical life, and the Holy Spirit with/in us, giving us spiritual life, even though we know God and have entered into the spiritual Kingdom of God in us, we still sometimes choose to live according to our fleshly spirit rather than the Spirit of God in us. That's why the Bible has so many warnings written for us, because those whom God loves He chastens in this life.
Ecclesiastes 12:14 (KJV) For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.
According to the words of Christ the Spirit of God was WITH the Old Covenant faithful before Christ's atonement. But after He resurrected and ascended to heaven He sent His Spirit to be IN men/women of faith. Every human is born with a spirit to give their body physical life. But only those who are born again through Christ's Spirit
with the Old Covenant faithful, and
in the New Covenant faithful have spiritual life through Him.
John 14:17 (KJV) Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
