A Sermon on Matthew 9:16-17
No one puts a piece of unshrunk cloth on an old garment, for the patch tears away from the garment, and a worse tear is made. Neither is new wine put into old wineskins. If it is, the skins burst and the wine is spilled and the skins are destroyed. But new wine is put into fresh wineskins, and so both are preserved.â (ESV)
These parables explained; many are outside the Church because of misconceptions concerning Christianity; a new and unique message; putting new wine into the old bottles (i.e. Ritualism); the power is entirely in the Gospel; not in man; the power that smashes man; then creates him anew.
