If the relationship is outpacing knowledge of character, reputation, and knowledge of godliness, then that is way too quick.
I am going to be real cautious about saying there is such a thing as “too fast.” What I would rather ask is this: What’s driving the speed?
If mere physical attraction or some kind of emotive, frilly, this-is-the-one weirdness is driving the speed, then, yes.
Any advice for inviting others into a relationship to that end? But I think what we want to do is work really hard in our churches to create a culture of discipleship.
I love this question because I’m such a big believer in what God has called the covenant community of his people to be in a local context. In this culture, the norm, the air we breathe, is that older men are serious about seeking out younger men to train them; not just train them in the Bible, but really train them in what it looks like to apply the Scriptures to their lives.
Because what I have tragically found is that Christian singles hit an area of desperation, particularly young women, and they will go: “Yeah, he is a Christian, he comes to church.” And really what they’re saying is this guy comes to church a couple of times a month, but outside of attending a service, he doesn’t have a real seriousness about growing in his understanding of the Lord, growing in his understanding of the Bible, being a prayerful person, no vivication or mortification that can be spotted, and no one who really knows them enough to speak to the growth in their character.
