It isn't always pleasant carrying out God's Word. Sometimes it's really uncomfortable.
Way back like 20 years ago or so (maybe longer even) I had a fellow classmate in one of my college classes. I knew she was involved in some things she shouldn't be involved in. I heard beyond any doubt from God in His Word that I needed to say something to her about this. I didn't want to but I was going to follow through and do what God told me to do.
I chickened out.
Sadly, I don't know what happened to her. We weren't ever close so even if I had said something I probably still wouldn't know where she was today. I don't even remember her name. But, maybe the word God wanted me to share with her (even though it was uncomfortable) could have gotten her back to where she should have been. Or, maybe she wouldn't have listened.
I'll never know.
