Anything or anyone that opposes Jesus or his relationship with people is an antichrist. We live in the world but that doesn’t mean we have to love the world. We have to be careful to not let our desires and aspirations take the place of or get in the way of God. What’s done for Christ will last. Is that thing you spend your money, energy and time on actually important? 

• Love for the world breeds corruption of the heart. 
• It's not sinful to want, it’s not sinful to have, it’s not sinful to achieve, but if we do so at the expense of our relationship with God, then we have loved the world and that is sinful.
• Like the game of telephone, the farther you get away from the original message, the more corrupted it becomes. 
• To deny Christ, while using Christ as the justification for your denial, makes you an antichrist.
