22 “No one puts new wine into old wineskins; otherwise the wine will burst the skins, and the wine is lost and the skins as well; but one puts new wine into fresh wineskins.” Mark 2:21-22.
As Christians, we are like new unshrunk cloths and new fresh wineskins. We are new creations. “Therefore if anyone is in Christ, he is a new creature; the old things passed away; behold, new things have come.” 2 Corinthians 5:17.
This is certainly “Good news!”. First, it is simply “Good news!” in the most common and simple meaning. Second, as you can see in the Scripture below, the word “new” is used many times to describe Christians and their life, and all these “new”s are good.
Consider all the good “new”s in the following Scripture:
Romans 6:4
“Therefore we have been buried with Him through baptism into death, so that as Christ was raised from the dead through the glory of the Father, so we too might walk in newness of life.”
Romans 7:6
“But now we have been released from the Law, having died to that by which we were bound, so that we serve in newness of the Spirit and not in oldness of the letter.”
2 Corinthians 3:6
“who also made us adequate as servants of a new covenant, not of the letter but of the Spirit; for the letter kills, but the Spirit gives life.”
“by abolishing in His flesh the enmity, which is the Law of commandments contained in ordinances, so that in Himself He might make the two into one new man, thus establishing peace,”
“and put on the new self, which in the likeness of God has been created in righteousness and holiness of the truth.”
“and have put on the new self who is being renewed to a true knowledge according to the image of the One who created him–‘
“BEHOLD, DAYS ARE COMING, SAYS THE LORD,
WHEN I WILL EFFECT A NEW COVENANT
WITH THE HOUSE OF ISRAEL AND WITH THE HOUSE OF JUDAH;
NOT LIKE THE COVENANT WHICH I MADE WITH THEIR FATHERS
ON THE DAY WHEN I TOOK THEM BY THE HAND
TO LEAD THEM OUT OF THE LAND OF EGYPT;
FOR THEY DID NOT CONTINUE IN MY COVENANT,
AND I DID NOT CARE FOR THEM, SAYS THE LORD.
FOR THIS IS THE COVENANT THAT I WILL MAKE WITH THE HOUSE OF ISRAEL
AFTER THOSE DAYS, SAYS THE LORD:
I WILL PUT MY LAWS INTO THEIR MINDS,
AND I WILL WRITE THEM ON THEIR HEARTS.
AND I WILL BE THEIR GOD,
AND THEY SHALL BE MY PEOPLE.
AND THEY SHALL NOT TEACH EVERYONE HIS FELLOW CITIZEN,
AND EVERYONE HIS BROTHER, SAYING, ‘KNOW THE LORD,’
FOR ALL WILL KNOW ME,
FROM THE LEAST TO THE GREATEST OF THEM.
FOR I WILL BE MERCIFUL TO THEIR INIQUITIES,
AND I WILL REMEMBER THEIR SINS NO MORE.”
When He said, “A new covenant,” He has made the first obsolete But whatever is becoming obsolete and growing old is ready to disappear.”
For this reason He is the mediator of a new covenant, so that, since a death has taken place for the redemption of the transgressions that were committed under the first covenant, those who have been called may receive the promise of the eternal inheritance.
“Therefore, brethren, since we have confidence to enter the holy place by the blood of Jesus, by a new and living way which He inaugurated for us through the veil, that is, His flesh,”
