What the Bible says about Mix and Match
(From Forerunner Commentary)

Matthew 9:16 "No one puts a piece from a new garment on an old one; otherwise the new makes a tear, and also the piece that was taken out of the new does not match the old" (Luke 5:36). Mark's version of the same parable stresses that the "tear is made worse" when the new patch eventually "pulls away from the old" garment (Mark 2:21). Christ's message is clear: When it comes to doffing the old man and donning the new one, we cannot "mix and match." Successfully mixing them—combining them—is as impossible as serving two masters. We just cannot do it (Matthew 6:24)! The two men represent intrinsically and irreversibly opposing ways of life.
