The implication from Revelation 2:2, 7 is that the works of which Christ is concerned are the works of overcoming—overcoming human nature or, as in I John 2:15-17, overcoming "the lust of the flesh, the lust of eyes, and the pride of life." In addition, we must work to overcome the persecutions, deceits, and persuasions of Satan and the influences of the world.
Using God's love is hard work because there is a constant downward pull in these three areas: the self, the world, and Satan. The influence to go that way is always there. It is constant.
It was no accident, no coincidence, that Christ places the message to Ephesus first in order, and that its subject is love in context with overcoming. Christ says in John 14:15, "If you love Me, keep My commandments." It takes the love of God to keep the commandments in the spirit—in their intent—and it is love working and active when they are kept. I John 5:3 says, "This is the love of God, that you keep His commandments." So, when we keep His commandments, we are expressing love. It is working, in action.
If a person's love for Christ—keeping the commandments—diminishes, what happens? If the love for Christ diminishes, does that not imply the keeping the commandments will be less frequent? Doing the right works will begin to diminish. Here is the connection between love and right works. If the love is present, the right works will be produced.
If a person loses his love for Christ altogether, he is in bad trouble—"Goodbye, Christianity! Sayonara!" That is the end.
