^{Gen. 3:6 "}When the woman saw that the tree was good for food, and that it was a delight to the eyes, and that the tree was desirable to makeone wise, she took from its fruit and ate; and she gave also to her husband with her, and he ate. ⁷ Then the eyes of both of them were opened, and they knew that they were naked; and they sewed fig leaves together and made themselves ^[b]loin coverings."

^{1 John 2:16 "}All the things the world can offer to you—the allure of pleasure, the passion to have things, and the pompous sense of superiority—do not come from the Father. These are the rotten fruits of this world." (The Voice)

one fruit
one lie
one choice

a feast 
for flesh 
for eyes

to gloat,
to glut
to prize

one heart
one mind
one voice

God offered Eve His world in love, to love Him. Eve grabbed at the world to love herself.
Anything you do that is ultimately motivated by devotion to yourself...your pleasure, your delight, your reputation...is an act of rebellion against your God. 
Eve's sin was not about the fruit. It was about Eve.
Selfishness can twist what God intended for good into evil- quick as you can say "ME". Worshipping ourselves makes us enemies of God. 
Telling ourselves that God exists to make us happy is not the Gospel. It is not good news if we are as big as the grand plan gets!
By all means embrace how God made you...because it honors Him.
By all means delight in the gifts He gives you...because they are from Him.
By all means make the most of the days He provides you...because they are for Him!
No, Victoria Osteen, God does not exist just to make sure you're happy. Believe it or not He is bigger than that.
Maybe,
"When you come to church and worship...think of it this way...yer not doin' it fer God, yer doin' it fer yerself....a-ME-in?"
But I want to choose to live for something, for Someone much bigger than me.

"Selfish ambition is a sin that always seems to be “crouching at the door” (Genesis 4:7). It contaminates our motives for doing just about anything..." Jon Bloom, DesiringGod.org
No one can serve two gods. 
Are you the only one you serve
or will you serve The One and Only?
