Nice to know that Jehovah doesn't penalize you or him for not being able to follow through thoroughly in this case. No doubt, after this co worker is resurrected, you will be able to do what you could not in this system and teach that co worker the truth about your loving, wonderful God!
I feel the same as you. Every talk, every Watchtower study reminds me I'm not good enough to survive Armageddon, and if I don't I am glad to of had the time I had serving Jehovah on this side of the new world. There are those in my congregation that have treated Jehovah's sheep terribly and then run away to another congregation (they are now back in my congregation again). Because of how serious and long and entangled the whole mess was, it seemed there was no justice but we did get relief when they left. Now that they are back, there is no accountability, no apologies. Just a pretense that they did nothing to no one. I trust in Jehovah (who saw and heard all their schemes) to provide justice and in the meantime, most of us in this congregation allow them their illusion of having done absolutely nothing wrong. We let them live their lie because if we didn't Satan could cause a lot more division and trouble in our congregation than he already has, so they are in Jehovah's hands. A very wise person once told me "you will be surprised who makes it (perhaps that will be those of us who aren't as confident!) and "surprised who doesn't" (those who think their sins are still concealed or forgotten by Jehovah). But I do feel, it won't be until after Armageddon that we won't realize how merciful (and perhaps, Just) Jehovah truly is.
