New Defender's Study Bible Notes
1:2 before the world. “World” here is aionios, from which we derive aeons; “began” is inferred, though the word is not in the original manuscript. The concept is that of a space/time continuum. The phrase could be read “before the space/time cosmos.” That is, God promised eternal life to His people even before our universe of space and time existed. The same concept is in II Timothy 1:9.
