One additional thing Donna as this is important to me and something you probably know already. I agree there are times to keep things to ourselves. We all have our weak moments, off days, and such, so I generally look to ignore these things. Even if that is how we are already, speaking or not speaking would depend on various things for me. How is someone to grow if something is not brought to their attention, including things with ourselves?
Yet, it is important not to try and change others of ourselves and mold them to our ideals. This is another reason why the simplicity in Christ and his cross is so important. Any other bridge between relationship that we try to establish will eventually fall apart with the right amount of pressure. It needs to be established foremost in Christ, picking up our crosses and following Him. That said, communication does help to bridge misunderstandings and repair relationships. Some questions we may ask ourselves is whether we are just looking out for ourselves, or looking to help the other out too, and the relationship itself. If we feel the need to speak, unless God tells us otherwise, we can, but we must leave the outcome to Him. Afterall, He may allow someone to remain blind to their issues, if they do indeed have an issue, because He is looking to do a work in us first.
Another thing to consider is timing...if the atmosphere is emotionally charge, it may be better to wait so we can view things more objectively in regards to what may be negative emotions.
I do take issue when others speak out against emotions as if they are bad and a hinderance (and do know I am not at all saying you are saying that as I didn't see you say that, just speaking of what I have come across). Sure, emotions can be the devil's playground, but they can be the Lord's playground too if we are coming from our Lord's Heart, a zeal for our Father, and secondary but hand in hand, for his people.
Just sharing some things I've learnt about these things, things you may know already.
Thanks sis, and thanks for looking out for me. I'm listening.
