Study Lenses
The verse centers on "commandments", "keeps", "loves", "shall", "loved", and "father". It is saying that the verse draws attention to "commandments" and "keeps", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 20's "In that day ye shall know that..." into verse 22's "Judas not the Iscariote says to him...", so "commandments" and "keeps" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "commandments" and "keeps" with trust shaped by these words, not by a vague optimism outside the passage.
