The evildoers running the Sanhedrin were now confronted with a real problem. The man they had unjustly murdered had come back from the dead—His greatest miracle. He ascended into Heaven and poured out the Holy Spirit on His twelve disciples, who began preaching the resurrection powerfully and performing many wonders and miracles (v. 43). By killing Jesus Christ, the unbelieving Jews only succeeded in giving Him a throne of everlasting dominion in Heaven. And down below in Jerusalem the headache that Jesus had been for them was now multiplied by twelve. In addition to this, because baptism was being administered in the name of this Jesus, the Church now had a definite set of boundaries. These were the people who were bound to Christ.
