I fundamentally agree with this.
As Christians our obedience should spring from our love for God and that's always been the case. Which is why Paul can say, examine yourself whether your in the faith.... Which is similar to words also among the first of Christ, Get the mote out of your own eye.
But telling unbelievers they have to be perfect, as many Gospel presentations do is that an accurate presentation of what's being said? Jesus isn't talking to unbelievers, but rather to believing Jews. He is not making a Gospel presentation. (Apologies to Ray Comfort, may God continue to bless his work.) I do think we should follow the Way of the Master but this was how he spoke to believers.
That's what this thread is/was about anyway. Thanks for chiming in.
God bless
