In the first verse, you would not need to do OBE at all, because Jesus could be right next to you in spirit, speak and he would hear you, right?
Are you at a spiritual level high enough to understand what happens if you were to go out of your body?
What would it have as use for you if you saw heaven, then suddenly you were back in your body, and you have to live your life in the body. Would it not create a longing to see it again. a so strong wish to see it again that you would only think of it, and feel miserable in your daily life, all the way to the day you passing away.
Could you handle the craving to see more but be unable to do it?
I do not say this to scare you, but the reality here on earth is not the same as in heaven, you may not even understand anything if you were granted only a peek in to the heavenly realm.
