There are different denominations because these denominations are limited. Baptists believe certain things, pentacostals believe another, catholics are just messed up, but mostly people who say they are christian, are not. God says love the lord thy god with all thy heart, soul and mind. This is 100%, yep, the way is indeed narrow. So many do not find this way and become once again children of wrath, frustrated, ignorant and opinionated, seeking to justify themselves in a world they have created, which is full of guilt. Catholicism has done a fairly good job at brainwashing believers with their pagan doctrines too. Most of my hubs are anti catholic doctrine which denominationalism has just adopted without checking it out.
Gods way is 100% prayer, neither the flesh nor the human spirit wants to do this, its difficult, but not impossible. So loving god is always out of reach without God doing the work in us and this job, He does, comes through our earnest desire that He change us and help us to pray, help us to love; because no person can force themselves into heaven, nor are their own works sufficiently good enough to produce admission to heaven. Therefore God can't bless these self-willed individuals with all revelation and spiritual knowledge because they simply aren't following the correct procedure. God is all about principles. If you do this I will do that. We must act first, be humble - you can tell the people in hubpages who are not humble lol, anyway, so until people get real with god and lose this life, even hate the things of this world and forsake all, pick up their cross and follow jesus with all their heart soul and mind the doctrines of christ will be muddled because he hides the truth from those who are not worthy. Did he not speak to the jews in parables? and when a worthy one comes along, generally the unsaved always ask the question: Is this not the carpenters son? and proceed to throw stones.
