We will not subject ourselves to a barrage of questions that are none of their business. What our heart condition is, is none of their business.
That is the best way, I feel, to approach this whole issue.
If making judgement calls on heart conditions is the job specifically of God and Jesus, just who do the GB think they are to assign by proxy the judgement of a persons heart condition. They are in fact not there to make a judgement call as to whether or not you love Jehovah or Jesus, they're there to test your loyalty to the WT organization. Too many people on the outside are still actually trapped because they still feel that they have to answer to nosy elder bodies.
The elders knocked on my door a couple of months ago. I yelled "GO AWAY" and made no move to answer the door. My wife, who's still a firm believer, went and answered the door and talked to them for a few minutes. She didn't volunteer to me what she said to them, but, they haven't been back. She's on notice that unless I initiate contact with them, I expect to be left alone.
