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.

(1 John 2:15-16).

 Apostle John was admonishing us to shun the lustful attraction of sin that draws one to perdition. "Love not the world" implies that followers of Christ should deviate from worldly lust or enticement.

The world represents the astronomical earth or the spiritual foundation of man. 

The astronomical earth reflects the earth and its system. That is, it describes the earth in relationship with the planet,  stars and satellites around the earth in our solar system. 

While the spiritual foundation of man is man's heart. 

I believe that the apostle was referring to man's heart or nature when he used term 'world'. While love points to the affection from man's heart. Our heart is an evaluation point of life, where we give value, calculate value and miscalculate value (deceived). 

The heart works in value hence John was trying to let us know the lust or deceit of the flesh, the lust or deceit if the eyes, and the pride of life is vainglorious and delusional. 

Love is true, but lust...(Whenever I see the word 'lust', I mark it as deceit. Lust means to be deceived by the desire of your flesh or your eyes.)

How Our Flesh Can Deceive Us

When your body start reacting you might have the urge to do certain things or may feel it's right to do certain things due to your feelings, biological programming or signals in your body.

How Our Eyes Can Deceive Us

When we see something our brain starts linking it up with our feelings, or other past experiences we might have had which can be very strong and tempting. We can make decision based in that.

How Can One Cease From Lust and Pride 

1. Don't be lead by your feelings.

Emotional people are easy to fool. As a Christian you need the senses of the Spirit of God, not you relying on emotion. Romans 8:14 says "As many that are lead by the Spirit of God they are the sons of God."

2. Always pray.

A lifestyle of prayer is a lifestyle of the Spirit of God. When you're active in prayer your emotion is not in control, but God's Spirit.

3. Read the word of God. 

The Bible is a book of God's knowledge. Reading the Bible opens your spiritual eyes. When your spiritual eyes are open, you will not be subject to the lust of the eyes. Psalm 119:18 says, "Open thou my eyes that I may behold the wonderous things out if they law."

4. You can go on a little fast. 

Fasting can make you live a devoted life to God. But you shouldn't overstretch your capacity. You can do it from morning till noon and break your fast with prayers offered to God. Please don't overdo it.

5. Be obedient. 

Obedience according to 1 Samuel 15:22 is better than sacrifice. No amount of what you do as a christian can replace obedience. Fasting, prayers, offerings, going to church can't. So obey the commandment of God, with that you will be disobedient to the dictate of the flesh.

Have a nice day!
