James 1:13 says "...God cannot be tempted by evil, nor does He tempt anyone." but don't ignore that James goes on to say, "But each one is tempted when by his own evil desires he is lured away and enticed." Jesus was never lured away or enticed by evil, even though evil attempted to entice Him.
And not giving in to evil, letting it rule over you, is the farthest thing from being weak. He did not bow to sin as you did.
You have the contradiction in positing that Jesus was tempted in every way as we are yet cannot be tempted in anyway as we are.
