To me, “gripping” is not a misspelling of “griping” but a term used to express worry. Either way, Christians aren’t supposed to do it.
I am constantly amazed when I am around Christians who complain, whether it’s about their families, their jobs, or their churches. When you put God in front of you in your life, those concerns about all those worldly things go away.
We need to show the world their need for a Savior and our appeal for Jesus by being different. That is, not griping, not gossiping, not nagging, not acting “holier than thou”. If people wonder why we’re griping all the time and know we follow Jesus, they will wonder why we would follow someone who isn’t satisfying whatever desire we are complaining about in that moment.
If people wonder why we’re joyful all the time and know we follow Jesus, they won’t care about whether or not our personal desires are being satisfied… they’ll just want to know how they can get some of that joy too.
