I am sorry. Maybe heretical is too soft a term. How about apostate ? Of course there can be no end to this if you infer certain "truths" from a non-contextual point of view. I do not subscribe to man's views on scripture. Man can, and does, twist scripture, to get his desired effect.
In the book of John, chapter 14, Jesus promises his disciples that he will come back for them after he goes to prepare a place for them. He then tells them again, "I will not leave you as orphans; I will come to you. Before long, the world will not see me anymore, but you will see me. Because I live, you also will live. " John 14:18,19
All of these guys he was talking to were martyrd, for their faith in God.
In John 17, Jesus prays to God, "I am coming to you now, but I say these things while I am still in the world so that they may have the full measure of my joy within them. I have given them your word and the world has hated them, for they are not of the world any more than I am of the world. My prayer is not that you take them out of the world but that you protect them from the evil one. They are not of it. Sanctify them by the truth; your word is truth. As you sent me into the world, I have sent them into the world. For them I sanctify myself, that they too may be truly sanctified. My prayer is not for them alone. I pray alo for those who will believe in me through their message, that all of them may be one, Father, just as you are in me and I am in you. May they also be in us so thet the world may believe that you have sent me. I have given them the glory that you gave ;me, that they may be one as we are one: I in them and you in me. May they be brought to complete unity to let the world know that you sent me and have loved them even as you have loved me ." John 17:13-23
Ask yourself why Jesus would tell them that the world hated them and was going to kill them and then say, "I'll be right back!" It is called encouragement. The world may destroy our flesh, but praise God, Jesus has overcome the world. Even Jesus did not know when he would return, but by saying soon he covered the bases. How long does a man live? While we live in the flesh, we will have troubles, "I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world ." John 16:33
