Here Rev. Suk contemplates whether it's possible God might have been deemed a narcissist by some, describing himself in scripture grandiosely as "Creator of heaven and earth" and who requires a true believer to love him "with all your heart,..soul..and mind".
No, rather John suggests that God's true interpretation of his commandments would have us love our neighbours and, though this may be the second commandment, it is the road to fulfilling the first - loving our God with all that we are. Now is the time to do just that. Whether in isolation, or not, let't take good care of one another.
