Self (self-centeredness and self–gratification) is at the heart of loving the world. Lust is confused with love and controls thinking, enflames emotions, and drives behavior.
The only healthy, purposeful, and fulfilling life is the one that is focused on God and walking out His plan and purpose in loving relationship.
Walking in the Spirit will subdue the base nature of the unregenerate soul. This is only possible as one becomes born-again by receiving Jesus Christ as both Lord and Savior.
Then, in response to the Father’s love, one can truly love God and not the world. Don’t be deceived. It is an absolute that you cannot love both. You will serve one or the other.
