1 Corinthians 15:45-58

So it is written [in Scripture], “The first MAN, Adam, BECAME A LIVING SOUL (an individual);” the last Adam (Christ) became a life-giving spirit [restoring the dead to life]. [Gen 2:7] However, the spiritual [the immortal life] is not first, but the physical [the mortal life]; then the spiritual. The first man [Adam] is from the earth, earthy [made of dust]; the second Man [Christ, the Lord] is from heaven. [Gen 2:7] As is the earthly man [the man of dust], so are those who are of earth; and as is the heavenly [Man], so are those who are of heaven. Just as we have borne the image of the earthly [the man of dust], we will also bear the image of the heavenly [the Man of heaven]. Now I say this, believers, that flesh and blood cannot inherit nor be part of the kingdom of God; nor does the perishable (mortal) inherit the imperishable (immortal). Listen very carefully, I tell you a mystery [a secret truth decreed by God and previously hidden, but now revealed]; we will not all sleep [in death], but we will all be [completely] changed [wondrously transformed], in a moment, in the twinkling of an eye, at [the sound of] the last trumpet call. For a trumpet will sound, and the dead [who believed in Christ] will be raised imperishable, and we will be [completely] changed [wondrously transformed]. For this perishable [part of us] must put on the imperishable [nature], and this mortal [part of us that is capable of dying] must put on immortality [which is freedom from death]. And when this perishable puts on the imperishable, and this mortal puts on immortality, then the Scripture will be fulfilled that says, “DEATH IS SWALLOWED UP in victory (vanquished forever). [Is 25:8] O DEATH, WHERE IS YOUR VICTORY? O DEATH, WHERE IS YOUR STING?” [Hos 13:14] The sting of death is sin, and the power of sin [by which it brings death] is the law; but thanks be to God, who gives us the victory [as conquerors] through our Lord Jesus Christ. Therefore, my beloved brothers and sisters, be steadfast, immovable, always excelling in the work of the Lord [always doing your best and doing more than is needed], being continually aware that your labor [even to the point of exhaustion] in the Lord is not futile nor wasted [it is never without purpose].
