How do I reconnect my old knob-and-tube wiring to a new box. My issue is my furnace will not come back on until the knob-and-tube wiring is connected to the new main breaker box. This is a temporary fix to a costly repair I cannot make until spring. But, I need heat now for the winter. So how do I reconnect the wires?

I agree with 3phase , the wiring in many old homes is still k&t , the junctions still require to be in a box , I was trained to use western union splices 7 turns minimum for both T taps and splices after wrapping they were soldered and this is still ok today , code states you can not use solder only the wrapping is the mechanical part. Since you are going from K&T to probably romex you may not have a box so you need a new box with insulated bushings for the wires to enter you will need a pair of knobs outside the box to anchor the wires through the insulators and into the box. I use shrink tubing But fiber insulation can be used then wire nut from the old to new and install the cover. This method will pass inspection as long as your AHJ allows , I did quite a few Over the years I only mentioned the turns because to meet historical accuracy that was required , wire nuts are better today since you are converting the panel.
