1Corinthians 15:46-47 “Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual. The first man is of the earth, earthy: the second man is the Lord from heaven.”
This section gets a little harder to me since we know that our resurrected bodies will arise from the dust of the ground. Verse 47 helps us draw the distinction between natural and spiritual. The natural man, Adam, was created from the dust of the ground and was dependent on the laws of nature as established by God for his existence; his sustenance was dependent upon God’s provision through the creation on earth. The spiritual man, Jesus Christ, though willing to humble Himself and be born of flesh as a man, is a supernatural being, a heavenly being. His willing sacrifice made it possible for man to be transformed into a heavenly being.
The life force of our earthly body is the blood.
Leviticus 17:11 For the life of the flesh is in the blood….
The life force of our heavenly body is the Spirit.
John 6:63 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
Romans 8:9-11 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness. But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.
Galatians 6:8 For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.
1Corinthians 15:48-49 “As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly. And as we have borne the image of the earthy, we shall also bear the image of the heavenly.”
I really liked the wording of the New Living Translation for these verses: Every human being has an earthly body just like Adam’s, but our heavenly bodies will be just like Christ’s. Just as we are now like Adam, the man of the earth, so we will someday be like Christ, the man from heaven.
I think Paul’s explanation of this truth in his letter to the Romans gives us a fuller understanding.
Romans 5:17–19 “For if, because of the offence of one man, death ruled through that one man; how much more will those receiving the overflowing grace, that is, the gift of being considered righteous, rule in life through the one man Yeshua the Messiah! In other words, just as it was through one offence that all people came under condemnation, so also it is through one righteous act that all people come to be considered righteous. For just as through the disobedience of the one man, many were made sinners, so also through the obedience of the other man, many will be made righteous.” (Complete Jewish Bible)
1Corinthians 15:50 “Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.”
We have determined that flesh and blood are descriptive of man’s natural body, and this corruptible body can have no part in God’s eternal kingdom. God’s kingdom is one of righteousness.
Hebrews 1:8 “But unto the Son he saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom.”
Romans 14:17 “For the kingdom of God is not meat and drink; but righteousness, and peace, and joy in the Holy Ghost.”
John 3:3 “Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.”
