Among spiritual connoisseurs, it's agreed that convection from the Holy Spirit is far superior to conventional conduction from the Holy Spirit. By keeping the sense of wrongdoing flowing, in a constant but gentle manner, convection of the Holy Spirit results in a more even guilt, with fewer cold spots and a shorter regret time. You can tell that you're under convection of the Holy Spirit if your conscience seems to ache in an especially even manner. Or if the still small voice sounds a lot like a fan.
The Holy Spirit most often operates by radiation, directly from God. However, modern spiritual science also offers convection of the Holy Spirit, conduction of the Holy Spirit, and the ultimate in convenience, induction from the Holy Spirit. Each has its advantages and disadvantages. Experts in Theodynamics are constantly developing new systems of remorse transfer.
Addendum: Those who entirely refuse the influence of the Holy Spirit,
including the Holy Spirit's conviction of sin, will experience a markedly less comfortable form of transfer in the form of eternal hellfire.
