Now whilst they were speaking these things, Jesus stood in the midst of them, and said to them: “Peace be to you; it is I, fear not” (Luke 24:36-47).

We see here the marvellous nature of the Lord’s glorified Body.

It could enter unseen, and then become seen. It could easily be touched, but Its nature is hard to understand.

The disciples were affrighted, and supposed that they had seen a spirit.

And therefore the Lord, that He might show us the evidence of His Resurrection, said: “Handle Me, and see; for a spirit hath not flesh and bones as ye see Me have”.

Therefore it was not by being in a disembodied state, but by the peculiar qualities of the risen and glorified Body that He had passed through closed doors (John 20:19).

For that which is touched or handled is a body.

We shall all rise again with our bodies. “But it is sown a natural body; it is raised a spiritual body” (1 Cor. 15:44).

The spiritual body is the finer, and the natural body is the grosser, besodden as yet by the corruption of earth.

Was not that a real Body, wherein remained those marks of His Wounds, those holes of the nail-prints, which the Lord bade His disciples to handle?

Hereby, also, He hath not only strengthened our faith, but also quickened our love, since we know that it has been His will to carry to heaven those Wounds which He bore for our sake…and which He plainly showeth to His Eternal Father the price of our freedom.

It is as marked with these Wounds and embracing the trophy of our salvation that the Father hath said to Him “Sit Thou at My right hand”.
