Calm, that is all that he could feel the first time reaching this form. Despite their aura swirling around like a wildfire, his mind, body, and spirit felt calm and collected as he adapts to this new form. 'So that was what having God ki is like' Jack would think to himself, as it heals small wounds on him, and those around him, and burning away any impurities.

This is Jack as a Super Saiyan God, and I've also had this form in the back of my mind for a long time, where he would reach the realm of the gods. In this form, any small wounds he has or those nearby would be healed as long as their heart is pure enough, but burn away things that are evil. The flame-like energy would swirl either with control or wildly depending on his own focus, which could drain his energy fast.
