Jesus had the authority and power to lay His life down.<br>He had the authority and power to take it up again.<p>Who is His Father who gave Him such commandment? His HolySpirit. Mat 1:18,20 Luk 1:35<p> So Jesus came by that authority and power by His own Spirit - the HolySpirit.<br>No other person was involved.<p>Remember, Jesus was not born with the SinNature.  He did not have a dead spirit as all descendants of Adam have.   He was born of the HolySpirit so His Spirit is the HolySpirit.
