Robertson's Word Pictures (NT)
Proving (dokimazwn). Testing and so proving.
The sincerity also of your love (kai to thv umeterav agaphv gnhsion). Old adjective, contraction of genesiov (ginomai), legitimately born, not spurious. A collection is a test of one's love for Christ, not the only test, but a real one.
