Don't keep the Joy to yourself alone.

Luke 2:10-11,17 KJVS
And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people.
[11] For unto you is born this day in the city of David a Saviour, which is Christ the Lord.
[17] And when they had seen it , they made known abroad the saying which was told them concerning this child.

Jesus is the source of our joy, our amazing new relationship causes us to rejoice everyday!

There were different sources of joy before Jesus came, but when the angel came, they talked about a "great joy" which came to the world because of JESUS.
This clearly shows the way to true, great joy.

The amazing thing I want to show us is the attitude of the shepherds, they refused to keep it to themselves, this good tidings(wonderful news)

Luke 2:17 NLT
After seeing him, the shepherds told EVERYONE what had happened and what the angel had said to them about this child.

They knew the implications of his birth, they knew deliverance have Come, and they refused to keep it to themselves but instead they went informing others.

You have this great joy in you because Jesus lives in you, and you can't afford to keep it to yourself.
Alot of people dress well around you, joke with you but still they haven't found this eternal source of joy, you are there at this particular time to share that joy!!
He came for them too!

Another example is the Samaritan woman
John 4:28-29 NLT
The woman left her water jar beside the well and ran back to the village, telling EVERYONE,
[29] "Come and see a man who told me everything I ever did! Could he possibly be the Messiah?"

Believer, you have to let this joy be known to others, contribute your quota in the work of the ministry.
No one lights a candle and put it under bushel.
