It may be too easy to separate this commandment out from the context from which it was delivered. We might think of love as warm fuzzy "good Sunday morning" fellowship doing charitable things for our hard pressed. The context is the giving of one's life. Peter understood this in the verses to follow but was unsure of the immediate implementation in regards to what he should be giving toward Jesus in His sacrifice.
We return to the theme of being willing to do good, having good intents, but lacking the resolve and resource to sustain such. It is only by the empowering of the Holy Spirit that such sacrifice and goodness can be made.
