that flesh and blood cannot inherit the kingdom of God;<quoted text>
Look in your Bible...
1 Thessalonians 4:
16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
1 Corinthians 15:
53 For this corruptible must put on incorruption, and this mortal must put on immortality.
54 So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
Plain enough for you?
Flesh and blood refers to the mortal body, so our present bodies in their current condition cannot enter into the kingdom of God. Our present physical organism cannot go to heaven. The idea of inherit is to take possession of.
