3.  And the following counter question may also be put to them.  “No man hath seen God at any time, the Only-begotten which is in the bosom hath declared him.” John i. 18.  What of the Father did the Only-begotten Son declare?  His essence or His power?  If His power, we know so much as He declared to us.  If His essence, tell me where He said that His essence was the being unbegotten? ἀγεννησία.  cf. Prolegomena on the Books against Eunomius, and p. 39 n.  When did Abraham worship?  Was it not when he believed?  And when did he believe?  Was it not when he was called?  Where in this place is there any testimony in Scripture to Abraham’s comprehending?  When did the disciples worship Him?  Was it not when they saw creation subject to Him?  It was from the obedience of sea and winds to Him that they recognised His Godhead.  Therefore the knowledge came from the operations, and the worship from the knowledge.  “Believest thou that I am able to do this?”  “I believe, Lord;” cf. Matt. ix. 28. and he worshipped Him.  So worship follows faith, and faith is confirmed by power.  But if you say that the believer also knows, he knows from what he believes; and vice versa he believes from what he knows.  We know God from His power.  We, therefore, believe in Him who is known, and we worship Him who is believed in.
