The temptation that came to Christ was from without, but for sin to take place there always has to be an inner response to the outer suggestion to sin. Since Jesus was divine, He could not respond to temptation. In fact, if Jesus Christ had mulled over a temptation to sin for even a moment, He would have been tainted by sin. So I have to say, “No, Jesus Christ could not have sinned, and therefore, Jesus Christ could not have responded.” Now the temptation was real, but for sin to take place there has to be an inner response to the outer suggestion to sin.
