And to that, I say, "hallelujah"!
Think of the joy that accelerated through these two kids hearts when they rededicated their lives to Jesus! They experienced a rejuvenated sense of passion for their savior that probably made them want to dance. And not like Kevin Bacon in Footloose,
but more like that of King David in 2nd Samuel chapter 6.
You may remember that story. David was exuberant beyond measure because the Ark of the Lord had been brought from the house of Obed-Edom to Jerusalem. And as the Ark of the Lord entered the City of David, he (David) was seen leaping and dancing before the Lord.
David's joy couldn't be constrained.
His wife was appalled with the way he presented himself, but David said to her, "I will celebrate before the Lord. I will become even more undignified than this, and I will be humiliated in my own eyes." I think the only way he would've "become even more undignified" was if he adorned himself in '70s garb, broke out a disco ball, and threw on "Stayin' Alive" by the Bee Gees.
David's effervescence is a perfect archetype of how we should worship God in our lives.
Just think of all the amazing things He has done for you. Think of how much grace He has showered upon you. Think of how much mercy He has provided for you (they're new every morning). Think of how much love He has shown you. Think of what He has sacrificed for you.
So, where's your joy level? Reflecting upon God's spiritual blessings in your life should make you jubilant, not a Debbie Downer.
It's okay to be joyful, it's okay to have a merry heart, and it's okay to parade both your joy and your merry heart. Just make sure you work on your dance moves.
