Likewise, I say to you, there is joy in the presence of the angels of God over one sinner who repents. Luke 15:10

I wonder what that sounds like; the rejoicing before God over a soul saved. That heavenly joy is a foreign sound to me. I have only experienced the sound from this end – the earth.
On Saturday, our church had Vacation Bible School. During the course of the day, two girls accepted Jesus as their Savior.
Everyone shouted at VBS.
At the announcement on Sunday, everyone shouted again.

I have heard people shout and rejoice over many different things. Just watch a football game. When a team scores their fans jumped to their feet, raise their hands, pump their fist, give each other high-fives, and rejoice.
Let their team fumble or miss a crucial field goal and the fans boo the players and call them names.

It’s not so with salvation. It is eternal. We don’t lose or fumble. And we don’t boo anyone for not accepting Jesus. We pray for them.
So… Rejoice in the Lord always. Again I will say, rejoice! Phil 4:4
