"He was “touched with the feeling of our infirmities,” because He “was in all points tempted like as we are.”
When He was tempted,
he felt the desires and the inclinations of the flesh, precisely as we
feel them when we are tempted.
“Every man is tempted, when he is drawn
away of his own lusts [his own desires and inclinations of the flesh] and enticed.” James 1:14.
All this Jesus could experience without sin; because to be tempted is not sin.
It is only “when lust hath conceived,” 
--when the desire is cherished,
--when the inclination is sanctioned, —only then it is that “it bringeth
forth sin.”
And Jesus never even in a thought cherished a desire, or
sanctioned an inclination, of the flesh.
*Thus, in such flesh as ours, He
was tempted in all points as we are, and yet without a taint of sin." A.T. Jones
