First Adam is living being, but last Adam(JESUS) is Life-giving Spirit: Ephesians 2:4-7 (NKJV)
“So also is the resurrection of the dead. The body is sown in corruption, it is raised in incorruption. It is sown in dishonour, it is raised in glory. It is sown in weakness, it is raised in power. It is sown a natural body, it is raised a spiritual body. There is a natural body, and there is a spiritual body. And so it is written, “The first man Adam became a living being.” The last Adam became a life-giving spirit.” 1 Corinthians 15:42-45 (NKJV)
We, who are born in the natural through the sinful lineage of first man Adam and became natural being, got to be Born Again into the righteous lineage of Last Adam — Jesus Christ and become a spiritual being. This transformation should take place when we come to church and meditate on the Word of Christ. We have not received the Word to live a moral life and be satisfied with material things. Our calling is higher than all the things we see and desire to have and whatever the pagans go after. Our minds should be set on things above, where in Christ Jesus we are seated. We should aim and try our best to receive the resurrected, immortal life JESUS set for us.
People took baptism for their dead expecting resurrection: 1 Corinthians 15:50-54 (NKJV)
“Otherwise, what will they do who are baptised for the dead, if the dead do not rise at all? Why then are they baptised for the dead? And why do we stand in jeopardy every hour? I affirm, by the boasting in you which I have in Christ Jesus our Lord, I die daily. If, in the manner of men, I have fought with beasts at Ephesus, what advantage is it to me? If the dead do not rise, “Let us eat and drink, for tomorrow we die!”” 1 Corinthians 15:29-32 (NKJV)
When we lead a pagan to be born again in Christ Jesus, they have a question in their minds thinking where their parents and ancestors went without knowing Jesus and it is disturbing. But here these verses are consoling to see that people took baptism for their dead too, so that they too be resurrected. Glory to God! God made a way for all to have immortality and to live with Him forever and ever through Jesus Christ, our Saviour.
We have the image of the man(Adam) of dust, later we will have the image of the Heavenly Man(JESUS): Revelation 11:15-19 (NKJV)
“However, the spiritual is not first, but the natural, and afterward the spiritual. The first man was of the earth, made of dust; the second Man is the Lord from heaven. As was the man of dust, so also are those who are made of dust; and as is the heavenly Man, so also are those who are heavenly. And as we have borne the image of the man of dust, we shall also bear the image of the heavenly Man.” 1 Corinthians 15:46-49 (NKJV)
So we, who are born again do not go to dust as our old self of the man from the dust, but go to heaven, as we are born of incorruptible seed of God, just like Jesus, the Heavenly Man. This is what the greatest reward we get when we are born again apart from health, wealth and angelic protection we get till we reach heaven. Our Home is in Heaven, so let us do everything that will accompany us to go to that place. All material possessions we have to leave behind. Only what we are doing for the Lord Jesus, winning souls for the Kingdom of Heaven and keeping all His Commandments in our personal lives, we can take with us to go to heaven. Let us all prepare ourselves to meet the Lord Jesus, after finishing all He has purposed in us to do.
