Those who know God understand that when certain ideas come to them it did not come from within them. They know it came from an external source, for God is His own being, the ultimate being.
God has the power to cross dimensions. For is heaven not another dimension? God created so many stars they cannot be counted and crosses an expanse so big it is immeasurable. This is something a mere human cannot do.
There are those that act as if they are god. These people are blinding themselves to the truth and disobeying God.
“You shall place no other gods before God,” says the first commandment. Saying you are god, you are placing yourself before the true God. This is an act of selfishness and as I have pointed out before, to me, selfishness is the ultimate sin; for from it all other sins germinate.
False gods are yourself, another person, money, your job, sporting events, etc. Giving something more time and recognition than God is breaking the commandment. We are told to do things in moderation. This mean in little segments of our time, but once it becomes the main thing in your life, it is idolatry. So people need to search their souls and decide where they stand with God.
