Salvation is by Christ

When Peter and John were on trial before the Jewish leaders for healing a lame man and preaching Christ, they were asked, “By what power, or in what name have you done these things?”

Acts 4:10-12 (NASB95)
10 let it be known to all of you and to all the people of Israel, that by the name of Jesus Christ the Nazarene, whom you crucified, whom God raised from the dead—by this name this man stands here before you in good health.
11 “He is the stone which was rejected by you, the builders, but which became the chief corner stone.
12 “And there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved.”
