Growing young...in Paradise.
I am the Alʹpha and the O·meʹga, the first and the last, the beginning and the end. Revelation 22:13

27 And God went on to create the man in his image, in God’s image he created him; male and female he created them. 28 Further, God blessed them, and God said to them: “Be fruitful and become many, fill the earth and subdue it, and have in subjection the fish of the sea and the flying creatures of the heavens and every living creature that is moving on the earth.”Genesis 1:27,28 Then the man said:“This is at last bone of my bones And flesh of my flesh.Because from man she was taken.”Genesis 2:2316 Jehovah God also gave this command to the man: “From every tree of the garden you may eat to satisfaction. 17 But as for the tree of the knowledge of good and bad, you must not eat from it, for in the day you eat from it you will certainly die.”
The world as it is now.
Wrinkles, grey hair, brittle bones, loss of stamina, forgetfulness, vulnerability to sickness, and finally death.
“Seventy years is all we have—eighty years, if we are strong; . . . life is soon over, and we are gone.”—PSALM 90:10, TODAY’S ENGLISH VERSION.
But in the coming paradise we will all grow young. Jehovah's original plan for healthy beautiful people who never age will be back in action.
He has made everything beautiful in its time. He has even put eternity in their heart; yet
mankind will never find out the work that the true God has made from start to finish.
Ecclesiastes 3:1
Let his flesh become fresher than in youth;
Let him return to the days of his youthful vigor.’
Job 33:25
At that time the eyes of the blind will be opened,
And the ears of the deaf will be unstopped.
At that time the lame will leap like the deer,
And the tongue of the speechless will shout for joy.
Isaiah 35:5.
