Is Satan the Devil the ruler of this world?

Here is what The Bible has to say in 1 John 5: 19 " The whole world is lying in the power of the wicked one". And Revelation 12: 9 indentifies the wicked one in these Words. " The original serpent, the one called Devil and Satan, who is misleading the entire inhabited earth".

So to answer your question: Satan the Devil is indeed the ruler of this world but we are all free to give him the power over our life.

There are only two ways. Jesus said in John 14: 6 " I am the way, the truth and the life. Jehovah God sent His only begotten Son to show us the way. John 3: 16 reads: " For God loved the world so much that he gave his only begotten-Son, so that everyone exercising faith in him might not be destroyed but have everlasting life."

Psalms 37: 29 reminds us that " The righteous will possess the earth and they will live forever on it".

2 Timothy 3: 16,17 explains that God's Word is beneficial for our teaching and setting things straight, so that we become fully competent, completely equipped for every good work.

Satan's world is full of destruction on every country of our planet
