From Spurgeon's Matthew: the Gospel of the Kingdom (published these days by Banner of Truth).
'Christ's death was the end of Judaism: The veil of the temple was rent in twain from the top to the bottom. As if shocked at the sacrilegious murder of her Lord, the temple rent her garments, like one stricken with horror at some horrendous crime. The body of Christ being rent, the veil of the temple was torn in twain .... Now was there an entrance made into the holiest of all by the blood of Jesus; and a way of access to God was opened for every sinner who trusted in Christ's atoning sacrifice.
See what marvels accompanied and followed the death of Christ' The earth did quake, and the rocks rent; and the graves were opened. Thus did the material world pay homage to him whom man had rejected, while nature's convulsions foretold what will happen when Christ's voice once more shakes, not the earth only, but also heaven.
These first miracles wrought in connection with the death of Christ were typical of spiritual wonders that will be continued till he comes again - rocky hearts are rent, graves of sin are opened, those who have been long dead in trespasses and sins, and buried in sepulchres of lust and evil, are quickened, and come out from among the dead and go unto the holy city, the new Jerusalem.'
