“No one patches an old cloak with a piece of unshrunken cloth, for its fullness pulls away from the cloak and the tear gets worse. People do not put new wine into old wineskins. Otherwise the skins burst, the wine spills out, and the skins are ruined. Rather, they pour new wine into fresh wineskins, and both are preserved." -Matthew 9:16-17
Like the patch of cloth or the wineskins, we too must make ourselves new, when the Word of God is sewn onto us and poured into our hearts. If we remain as our old selves and refuse to change, we will not live the Truth revealed to us. If we toss away our old selves and accept the Gospel, that is when our life begins.
