Have the Elders read to you from their copy of the NWT John 6:66-69
"66 Owing to this many of his disciples went off to the things behind and would no longer walk with him. 67 Therefore Jesus said to the twelve: “YOU do not want to go also, do YOU?” 68 Simon Peter answered him: “Lord, whom shall we go away to? You have sayings of everlasting life; 69 and we have believed and come to know that you are the Holy One of God.
After they read that to you then ask them,since verse 66 plainly says many of his disciples went off to the things behind
and would no longer walk with him, how many of them did Jesus ask to sign something showing they no longer followed him?
If it was good enough for Jesus not to make his own disciples that left him sign something, then shouldn't the same be
true today?
