Study Lenses
The verse centers on "leaned", "iesus", "breast", "saide", "vnto", and "lord". It is saying that the verse draws attention to "leaned" and "iesus", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 24's "To him beckened therefore Simon Peter that..." into verse 26's "Iesus answered He it is to whome...", so "leaned" and "iesus" 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 "leaned" and "iesus" with trust shaped by these words, not by a vague optimism outside the passage.
