From the looks of them in the picture, they could BOTH use some fasting time. And, if they did, they should not be going around announcing it to the world:
"And when you fast, don't make it obvious, as the hypocrites do, for they try to look miserable and disheveled so people will admire them for their fasting. I tell you the truth, that is the only reward they will ever get." (Matthew 6:16)
I kinda think that principle applies to couples who want to "give up sex" for the sake of the Kingdom of God, too.
I agree; they should not be announcing this. I would imagine they’ve already received a “talking to” in this regard.
