<p>4:3 <em>And he that sat on it was to look upon like a jasper stone, and a sardius; and there was a rainbow round about the throne, like an emerald to look upon</em>- The rainbow suggests that Divine judgment has come to an end, and the faithful remnant saved. As noted on :1, this is a picture of things at the last day. The Lord sits upon the judgment throne with a rainbow as a halo around it, meaning that His judgment is overarched by grace and a desire in fact not to condemn the world, even if they spurn His grace and choose His condemnation.</p><p>Jasper is the gem used to describe the appearance of all the faithful (21:11,18,19); the Lord's righteousness and exalted status will finally be true of all who are in Him. The sardine or sardius likewise (21:20), and the emerald (21:19). These are also stones in the High Priestly breastplate, representing the tribes of the Lord's people. We, His people, shine from His face. This is the extent of His total identification with us, and ours with Him. See on 5:3.</p>
