Alisa and I were both wondering that same thing while visiting dad's grave site the other day. I asked her what she thought and she said something like "I don't know. I've been trying to understand that too." I'm not sure if anyone else has been thinking about this or not. I guess no one will know the exact, literal, most accurate answer until we join him in heaven but hopefully this helps someone else like it's helped us:
1 Corinthians 15:35-58 (some verses skipped)
"35 But someone may ask, "How are the dead raised? With what kind of body will they come? 36 How foolish! What you sow does not come to life unless it dies. 37 When you sow, you do not plant the body that will be, but just a seed, perhaps of wheat or of something else. 38 But God gives it a body as he has determined, and to each kind of seed he gives its own body. 39 All flesh is not the same: Men have one kind of flesh, animals have another, birds another and fish another...41 The sun has one kind of splendor, the moon another and the stars another; and star differs from star in splendor.
42 So will it be with the resurrection of the dead. The body that is sown is perishable, it is raised imperishable; 43 it is sown in dishonor, it is raised in glory; it is sown in weakness, it is raised in power; 44 it is sown a natural body, it is raised a spiritual body.
If there is a natural body, there is also a spiritual body...50 I declare to you, brothers, that flesh and blood cannot inherit the kingdom of God, nor does the perishable inherit the imperishable...55 "Where, O death, is your victory? Where, O death, is your sting?"
56 The sting of death is sin, and the power of sin is the law. 57 But thanks be to God! He gives us the victory through our Lord Jesus Christ.
58 Therefore, my dear brothers, stand firm. Let nothing move you. Always give yourselves fully to the work of the Lord, because you know that your labor in the Lord is not in vain."
Daddy, even though your body was "sown in weakness, it is raised in power". Love you so much.
