In this situation, I would have probably caved and “betrayed Christ” more than you did, OP. That being said, I think you did the best you could given the situation. Hindsight is a great teacher, am I right?
After having given this some contemplation, though, I think I would have said the truth - the full truth, including the emotional situation. Something I’m learning to do these days is rely on my emotions because people react very well to “I statements.” You were put in a bind on the spot, right? So say that. You didn’t know why they would gang up on you? Tell them! You don’t deserve to be treated this way, because you are a cherished child of God (well, you all are, but you’re the one being persecuted here).
I’m not quite sure what I would have done, but I’m pretty sure I could only make it worse for the female friend. The most likely targets to evangelize, then, would be your workmates - if they know you can stand up for your faith, they might take you more seriously and possibly even look into the Church. Don’t forget to pray for them too! I might give a closed-mouthed smile to the friend and if the situation got awkward, add, “What do you expect me to say?” Whatever you do, don’t give them what they want - that’s how bullies thrive. Help the bullies and yourself towards God by sticking to the Truth, and only the full Truth. That can’t lose.
I’ll be praying for you and your team. :byzsoc: Stay strong!
