Adam Clarke on Acts 4:12

Neither is there salvation in any other - No kind of healing, whether for body or soul, can come through any but him who is called Jesus. The spirit of health resides in him; and from him alone its influences must be received.

For there is none other name - Not only no other person, but no name except that divinely appointed one, Mat 1:21, by which salvation from sin can be expected - none given under heaven - no other means ever devised by God himself for the salvation of a lost world. All other means were only subordinate, and referred to him, and had their efficacy from him alone. He was the Lamb slain from the foundation of the world; and no man ever came, or can come, to the Father but by him.
