He didn't have help, He did it Himself. We need His help. We can know we have the Holy Spirit may be a different topic because being a Pentecostal, I would say by the initial evidence of speaking in tongues.Yes indeed...being fully human Jesus would have had the propensity to sin as we have but He also had help not giving in to it. How can we be certain to have GOD's Holy Spirit to help ? and how much or how little of it have we really got ?
