Understandable that you were busy. Next time why let them off that easy?
If JWs want to share a Bible verse with you, share one back like John 6:60-70. Then ask them, "If Jesus did not shun his disciples who left him or order his disciples who stayed with him to shun those who left, why does the Watchtower promote shunning JWs who no longer believe that the WTBTS knows the Truth?"
If JWs want to share a Watchtower or Awake! with you, ask them if they would like you to read them something from Raymond Franz's books (i.e., "Crisis of Conscience" or "In Search of Christian Freedom") or Steve Hassan's books (i.e., "Combatting Cult Mind Control", "Releasing the Bonds: Empowering People to Think for Themselves", or (his latest book) "Freedom of Mind: Helping Loved Ones Leave Controlling People, Cult and Beliefs"). You might plant a seed of doubt in a JW and your address will definately be put on the "Do Not Call" list.
Peaece be with you and everyone, who you love,
New International Version (NIV)
Many Disciples Desert Jesus
60 On hearing it, many of his disciples said, “This is a hard teaching. Who can accept it?”
61 Aware that his disciples were grumbling about this, Jesus said to them, “Does this offend you? 62 Then what if you see the Son of Man ascend to where he was before! 63 The Spirit gives life; the flesh counts for nothing. The words I have spoken to you—they are full of the Spirit [ a ] and life. 64 Yet there are some of you who do not believe.” For Jesus had known from the beginning which of them did not believe and who would betray him. 65 He went on to say, “This is why I told you that no one can come to me unless the Father has enabled them.”
66 From this time many of his disciples turned back and no longer followed him.
67 “You do not want to leave too, do you?” Jesus asked the Twelve.
68 Simon Peter answered him, “Lord, to whom shall we go? You have the words of eternal life. 69 We have come to believe and to know that you are the Holy One of God.”
70 Then Jesus replied, “Have I not chosen you, the Twelve? Yet one of you is a devil!”
