<p>2:36 <i>Therefore, let all the house of Israel know for certain, that God has made him both Lord and Christ, this Jesus whom you crucified</i>- Peter&rsquo;s growth of understanding of Jesus as &lsquo;Christ&rsquo; grew. He declared Him as this during His ministry (Jn. 6:69), and also as &lsquo;Lord&rsquo;, but he preached Him as having been <i>made </i>Lord and Christ after the resurrection (Acts 2:36). He saw the Lord&rsquo;s status as having changed so much, even though he used the same words to describe it, and therefore he responded the more fully to Him. He so often refers to the Name of Christ, which had now been given Him (Acts 4:12 RV)- as if this new Name and the redemption in it was the motive power for his witness. Jesus had been born a Saviour, Christ the Lord (Lk. 2:11). But Peter uses each of these titles as if they had been given to the Lord anew, after His resurrection. And indeed they had been. They were no longer just appropriate lexical items for Peter to use; they were the epitome of all that the Lord was and had been and ever would be, all that He stood for and had enabled. And he preached them to men as the basis upon which salvation and forgiveness was now possible. See on Acts 5:31.</p>
