Cheap grace is for those lazy so-&-so's that rebel from commitment, obedience, & the Lordship of Christ.
They want a savior, but not a Lord. Jesus can only come into your heart & save you as a packaged dead.
I would say that actually there is no such things as cheap grace.
We actually know the grace offered by God came as a result of a great price paid.
I would say it's actually treating Grace cheaply.
I think this is what Paul addressed
Romans 5:20 - 6:2
Moreover the law entered that the offense might abound. But where sin abounded, grace abounded much more, so that as sin reigned in death, even so grace might reign through righteousness to eternal life through Jesus Christ our Lord.
What shall we say then? Shall we continue in sin that grace may abound? Certainly not! How shall we who died to sin live any longer in it?
He then goes on to reveal the price
Romans 6:3-4
Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death? Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life.
The death of Jesus.
I have actually sin this in action myself.
A couple I knew were sleeping together before marriage with the attitude of "It's ok we are forgiven or will be forgiven"
Shocking attitude.
Part of of the problem today is that maybe the church is not preaching to price paid for grace and what it truly means to be a follower of Jesus.
But we need to separate what true saving faith is and what is not and as we can see there are differences of opinion.
Having said that though to me it can happen that people do not walk in the way of the commitment they have said they made BUT that doesn't necessarily mean they are not saved.
We need to come alongside and find out why.
My very simple example for me was before I became a Christian I used to read my horoscope. I became a Christian but still read my horoscope. When someone realised this (because I said to them "my horoscope said today) he took me to task, in a loving way.
I think further that if a person does stumble the Father will pick them up.
One thing I have seen and concerns me is that there is lack of true Christian birthing process.
What it actually means to be a believer and a true believer would never Jesus as a one way ticket to heaven regardless of what we do without regard to him.
