Love not the world

1 Corinthians 1:18

“For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God.” NIV

The third thing you die to is the world.

“But God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world.” Galatians 6:14 KJV
What is the world, you ask?

“Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him. For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world. And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever.” 1John 2:15-17 KJV

“Don't love the world's ways. Don't love the world's goods. Love of the world squeezes out love for the Father. Practically everything that goes on in the world — wanting your own way, wanting everything for yourself, wanting to appear important — has nothing to do with the Father. It just isolates you from him. The world and all its wanting, wanting, wanting is on the way out — but whoever does what God wants is set for eternity.” THE MESSAGE

“Stop loving this evil world and all that it offers you, for when you love these things you show that you do not really love God; for all these worldly things, these evil desires-the craze for sex, the ambition to buy everything that appeals to you, and the pride that comes from wealth and importance-these are not from God. They are from this evil world itself. And this world is fading away, and these evil, forbidden things will go with it, but whoever keeps doing the will of God will live forever.” TLB
James 4:4

“You [are like] unfaithful wives [having illicit love affairs with the world and breaking your marriage vow to God]! Do you not know that being the world's friend is being God's enemy? So whoever chooses to be a friend of the world takes his stand as an enemy of God.” AMP

When you are dead to the world, you do not get involved with the rat race that people get into, you do not get into bondage of the fashion of the world or the world’s system of doing things.
