The myth of Jesus is so fragile that missing a couple of months of indoctrination could allow you to realize the silliness of it all. Magic blood, a human that lives inside your biological anatomy, an invisible man that you can talk with, the oogie boogie hell story, the la la land of heaven's fair home and the terrible state of your heart just seems to stop making sense after missing a few church services. Until then, those fairy tales are real as sweet iced tea.

By any chance are you rationalizing your not attending church? There is no myths and magic involved, not if we go back to the basics. The first thing that we as individuals have to come to terms with is whether we believe human beings are made up solely of body and mind/brain, or if there is a third element--spirit/soul. Those of us who believe there is the third element of spirit in human beings believe that the spirit is eternal. Along with nourishing and building mind and body, we build and nourish the spirit.
Jesus said he could nourish our spirits through his own body and blood in the form of bread and wine--and through his words. We receive the Lord with everything we are, with our body, with our mind, with our spirit. Sometimes, with prayer, words are not enough. I find one of the most powerful forms of prayer is contemplation, where one simply clears all words from the mind (to the extent possible) and allow everything to work out in the silence. Let God search heart/spirit in the science, know what they need and then allow the renewed spirit to work from within.
Heaven, quite simply, is an eternal life with God living in the ways of God. The other life is a choice to do without God and His ways, and to be totally on one's own, without any help, which we have shown in this life that we have no use for and do not want. I often think of it as a choice of being a servant of God or being totally my own master. I am good with the choice of servant and student because even in this life, as good as it is, I often feel inadequate. I would gratefully accept the help of God/heaven and in turn be of help/service to God and others.
Blessings upon your own journey. Give the choice of spirit a chance, and if you truly end up in the belief that it is only body and mind--this life is still a miracle for all of us to enjoy.
