Please describe how you would imagine the "initial contact" would occur that would not be considered force feeding, harrassment or proselytizing. Just curious how you envision this.
Bill: Hey John, how's it going?
John: Good, you?
Bill: Great, God is good! Makes me feel like I should share the blessings I have been given. John, would you like to talk about faith?
John: No thanks Bill.
Bill: Ok, well if you ever do, just let me know.
Nothing forced there. But that because Bill backed off when John said no.
The example of harrassment would be more along the lines of:
Bill: Hey John, how's it going?
John: Good, you?
Bill: Great, God is good! Makes me feel like I should share the blessings I have been given. John, would you like to talk about faith?
John: No thanks Bill.
Bill: John, you never know when it's your time. You don't want to go to hell do you?
John: I'm just not comfortable with this Bill.
Bill: Well John, it's going to be much worse when your burning in the fires of hell for eternity. You need to hear what I have to say now. I'm only concerned for your soul.
John: Bill I said now...
Ok, so you can see where that goes.
Now maybe Bill is secure in his faith in both examples, and maybe Bill is concerned for John's wellbeing in both case.... but in the first case Bill says something and when John tells him no, he lets it drop. In the second case he continues to pursue. That continued push IS harrassment. The first example.... is not.
