The earth is the Lord’s and everything in it. The world’s systems is the devils: lustful/worldly or people without God.
When you are full of the Word, you will not fall in the world, in the ungodly, carnal system where the possessions/worldly things has the ungodly.
Sign of the last days: sin (missing the mark, grieving the Holy Spirit, disobedience to the Word of God or His will and iniquity.) There is a way out, just repent and change. When you do wrong, you should feel bad, be humble to repent, apologize, have natural affection. Whenever you are losing natural affection, you start doing what is against nature, iniquity becomes inbuilt, pride rules you and affects your relationships.
The world is an order of the world, government, order, constitution.
