New clothes, new wine, new bottles

Mark 2:21, 22 "21 No man also seweth a piece of new cloth on an old garment: else the new piece that filled it up taketh away from the old, and the rent is made worse. 22 And no man putteth new wine into old bottles: else the new wine doth burst the bottles, and the wine is spilled, and the bottles will be marred: but new wine must be put into new bottles."

Meaning:

Piece of new cloth and the new wine: The Gospel
Old garment and old bottles: Unconverted heart

The new cloth and the new wine=Gospel needs of new garment and new bottles = converted heart.

However, does not the Gospel have as a result a converted heart?

I thought Christ was referring to the old and new covenants. sewing them together would be like faith + works = salvation, when the new covenant is salvation by faith alone and works are the fruit of faith, not the precurser to it

yes your heart starts to change once you start to read and understand the Gospel.

I'd like to know more about that information regarding the old and new covenant related to those verses. Very interesting.
