Lust of the Flesh. Lust of the Eyes. Pride of Life.
"Do not love the world, nor 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 and the lust of the eyes and the boastful pride of life, is not from the Father but is from the world. And the world is passing away, and also its lusts; but the one who does the will of God abides forever."
LUST OF THE FLESH. Our physical, animal appetites, cravings, passions.
"the woman saw that the tree was good for food" (Genesis 3:6)
LUST OF THE EYES. Self-interest. Selfishness.
"and that it was a delight to the eyes" (Genesis 3:6)
PRIDE OF LIFE. Self promotion. Self exaltation.
"and that the tree was desirable to make one wise" (Genesis 3:6)
These 3 channels of TEMPTATION are Satan's hooks to guarantee that what we think we want and need outside of God's will can satisfy us.
A primary issue is deception. Once Satan gets you hooked with his deception, he'll leave you destroyed. You can never satisfy the carnal desires of the flesh, the lust of the eyes, or the pride of life. The more you feed them, the more they grow.
Only in Christ can you be truly satisfied. "Blessed are those who hunger and thirst for righteousness, for they shall be satisfied" (Matthew 5:6). By living by the power of the Holy Spirit, you and I will be satisfied.
