Adam’s one act made us all sinners, we all suffer the consequences.
1 Corinthians 15:21 - 22 (NKJV) 21For since by man came death, by Man also came the resurrection of the dead. 22For as in Adam all die, even so in Christ all shall be made alive.
1 Corinthians 15:45 - 48 (NKJV) 45And so it is written, “The first man Adam became a living being.” The last Adam became a life-giving spirit. 46However, the spiritual is not first, but the natural, and afterward the spiritual. 47The first man was of the earth, made of dust; the second Man is £the Lord from heaven. 48As 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.
We gain much more in Christ than we lost in Adam.
