I've never denied that I can be harsh sometimes. In fact, I admit it quite often. But even Jesus was quite harsh sometimes, to the point of "searing" words.
Blue. Unfortunately I hear self justification as if you are the righteous anger of the Lord, when you are not.
Jesus only got angry over either speaking words that the enemy intended or abuse of sacred ground.
Jesus is very careful about anger in the sermon on the mount. It is so strong I find it hard to take in.
"But I tell you that anyone who is angry with a brother or sister will be subject to judgment." Matt 5:22
But when I began to think more deeply about it I realised I cannot stand in judgement over another unless it is obviously sin. Brothers and sisters share from their hearts, and often the words can convey meaning they did not intend.
Equally who am I to say the Lord did not intend this to be shared in this way.
All I can do is reflect how things come across to me.
In our house group we have a counsellor who suggested doing a course on grieving. A lot of people have in the church lost people close to them and not come to terms with it. A friend was sharing with someone about this course and it came out that this other person had an issue about it. Since then they have been going along to discover what is happening and work through their experience.
Unfortunately harshness often causes such issues to stay hidden and lost. So I want to encourage you, to be careful about these things and encourage those who have something to share, to just share and wait to see what it might bring.
Harshness also often goes back to a root of bitterness and pain that is unresolved. So all I can suggest is to work through such issues, because only blessing can come as a result.
So I think harshness like this is sin and Jesus talks against it, the apostles etc. So be careful how you tread.
