Pr 15:1 A soft answer turneth away wrath: but grievous words stir up anger.
Have you ever considered your words to others and how they sound? What makes our words grievous to the point of stirring anger in another person? Why would we as Christians want to upset someone else by not even considering what it is that we are saying to that person that is grievous.
The bible says that if anyone lacks wisdom let him ask of God. It also says to follow peace with all men and holiness without which no man shall see the Lord. He tells us blessed are the peacemakers for they shall be called the children of God.
The next time someone disagrees with you, why not try to see why they disagree. In other words try to see there side instead, and work from there instead of trying to force your understanding on them.
Maybe in the end, even though we may not agree fully, we can see where they are coming from and at least be at peace with one another.
Blessings to all!
