Romans 12:1-2 NKJV
I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service.  And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
1 John 2:15-17 NKJV
Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him.  For all that is in the world-the lust of the flesh, the lust of the eyes, and the pride of life-is not of the Father but is of the world.  And the world is passing away, and the lust of it; but he who does the will of God abides forever.
John 18:36 NKJV
Jesus answered, “My kingdom is not of this world. If My kingdom were of this world, My servants would fight, so that I should not be delivered to the Jews; but now My kingdom is not from here.”
Matthew 6:19-21, 24 NKJV
“Do not lay up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal;  but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal.  For where your treasure is, there your heart will be also.  “No one can serve two masters; for either he will hate the one and love the other, or else he will be loyal to the one and despise the other. You cannot serve God and mammon.
WHO DO YOU SERVE?
1 Timothy 6:7 NKJV
For we brought nothing into this world, and it is certain we can carry nothing out.
