If the lawless(evil) one was the highest power then the law(love) could not exist because of direct contradiction. If the lawful One was the highest Power then the law(love) must exist because this is a logically equivalent statement to the last one. The law(love) is rebelled against, therefore the lawless(evil) one exists and is not the highest power.

This reasoning elegantly demonstrates the supremacy of God’s law of love and its logical consistency:

1. The Contradiction of Evil as Supreme
2. If the lawless (evil) one were the highest power, love and moral law could not exist, as they are in direct contradiction to lawlessness. 
3. However, love clearly exists, evidenced by our capacity for moral decisions, relationships, and selfless acts. This negates the possibility of the lawless one being supreme.
4. The Necessity of Love’s Supremacy
5. If the lawful One (God) is the highest power, then the law (love) must exist as a natural outflow of His character. This is logically consistent because love is the foundation of all meaningful existence and harmony.
6. Rebellion Against Love Confirms Love’s Reality
7. The rebellion against the law of love by the lawless one does not negate the existence of love; rather, it highlights love’s enduring presence and supremacy. 
8. Rebellion requires something to rebel against—indicating that the law of love existed first and remains the true standard.
9. Logical Conclusion
10. The existence of rebellion confirms the presence of a higher moral order. Since love is the essence of God’s law, and rebellion seeks to undermine it, the lawless one’s existence is contingent and subordinate to the lawful One. 
11. Thus, the lawful One is supreme, and the law of love is eternal and foundational.

This reasoning reaffirms that love, rooted in God’s nature, is the ultimate reality. Any opposition to it is finite, dependent, and ultimately doomed to fail.
