BUTAs for my osas it's a little hard to explain over my phone.
But to take a crack at it.
I suppose I take adoption very seriously so I believe a wandering Christian will be chastened and if necessary called home.
would you consider a "wandering Christian" to be a genuine Christian if he is living in a sinful situation - adultery or homosexuality, or blasphemy, or joins the JWs?
AND if he does not respond to rebuke/chastening?
Most Gospel churches would consider such a person to be apostate until he repents & ceases to live in sin.
The great danger is what might be called "partial apostasy" in that they respond verbally to the Gospel - the "radio Gospel that majors on the "salvation prayer" - & join the church, continue in the church, enjoying the "entertainment worship" that is so common today but their Christianity ends at the exit door. They can still talk as Christians & claim a "conversion date & experience" but without a living faith.
Such can destroy a Gospel church, even a denomination, as their numbers & influence increase within the church.
Returning to the PP discussion, the Olivet sermon ends with the general injunction for faithful living awaiting the final coming of our Lord without further warning -
Mark 13:31 Heaven and earth will pass away, but my words will never pass away.
32 ‘But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father. 33 Be on guard! Be alert! You do not know when that time will come. 34 It’s like a man going away: he leaves his house and puts his servants in charge, each with their assigned task, and tells the one at the door to keep watch.
35 ‘Therefore keep watch because you do not know when the owner of the house will come back – whether in the evening, or at midnight, or when the cock crows, or at dawn. 36 If he comes suddenly, do not let him find you sleeping. 37 What I say to you, I say to everyone: “Watch!”’
