John 3:16 – The Bible (KJV) – For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
John 16:33 – The Bible (KJV) – These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.
Language is how we communicate. Translations from one language to another can be complex. Also, words may have more than one meaning in any language, for instance, notice two uses of the word world in the above scriptures:
John 3:16 – world – the whole body of living persons –
John 16:33 – world – the universe especially when it is understood as an ordered system –
God loves people, as in John 3:16.
The world system is the cosmos, or the complicated situations in which we live, as referred to in John 16:33. Jesus has overcome the world systems and troubles that bind us.
