This long passage may be sufficient to answer the question.
1 Corinthians 15:35-54 (NIV)
But someone will ask, “How are the dead raised? With what kind of
body will they come?” How foolish! What you sow does not come to
life unless it dies. When you sow, you do not plant the body that
will be, but just a seed, perhaps of wheat or of something else.
But God gives it a body as he has determined, and to each kind of seed
he gives its own body. Not all flesh is the same: People have one
kind of flesh, animals have another, birds another and fish another.
There are also heavenly bodies and there are earthly bodies; but
the splendor of the heavenly bodies is one kind, and the splendor of
the earthly bodies is another. The sun has one kind of splendor,
the moon another and the stars another; and star differs from star in
splendor.
So will it be with the resurrection of the dead. The body that is
sown is perishable, it is raised imperishable; it is sown in
dishonor, 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.
If there is a natural body, there is also a spiritual body. So it
is written: “The first man Adam became a living being”; the last
Adam, a life-giving spirit. The spiritual did not come first, but
the natural, and after that the spiritual. The first man was of the
dust of the earth; the second man is of heaven. As was the earthly
man, so are those who are of the earth; and as is the heavenly man, so
also are those who are of heaven. And just as we have borne the
image of the earthly man, so shall we bear the image of the
heavenly man.
I declare to you, brothers and sisters, that flesh and blood cannot
inherit the kingdom of God, nor does the perishable inherit the
imperishable. Listen, I tell you a mystery: We will not all sleep,
but we will all be changed — in a flash, in the twinkling of an eye,
at the last trumpet. For the trumpet will sound, the dead will be
raised imperishable, and we will be changed. For the perishable
must clothe itself with the imperishable, and the mortal with
immortality. When the perishable has been clothed with the
imperishable, and the mortal with immortality, then the saying that is
written will come true: “Death has been swallowed up in victory.”
Many protestant preachers say that our body will be reconstructed from the remains of our body from the grave or where ever it is. The one that was blown up in a bomb explosion will also be recollected and rebuild from ashes. But it will be transformed to a heavenly body. That is what exactly this passage is talking about. The heavenly body will not look the same like the old one. A person who was born without legs will have two perfect legs. A blind person will no longer be blind and the deaf person will hear too.
I heard from many protestant preachers that the reason why Jesus still has the scars on his body is to keep it as a remembrance that Jesus suffered and died for us. The scars were left there intentionally on purpose.
