Great reason we should be heavenly in our thoughts, affections, conversation, if we consider what a blessed kingdom heaven is. It is beyond all hyperbole. Earthly kingdoms scarce deserve the names of cottages compared with it. We read of an angel coming down from heaven, who set his right foot upon the sea, and his left foot on the earth. Rev 10: 2. Had we but once been in the heavenly kingdom, and viewed the superlative glory of it, how might we, in holy scorn, trample with one foot on the earth, and with the other foot upon the sea? There are rivers of pleasure, gates of pearl, sparkling crowns, white robes; and should not this make our hearts heavenly? It is a heavenly kingdom, and such only go into it who are heavenly.
Thomas Watson, The Lord’s Prayer
