What a fantastic story! We see the Israelites on the verge of civil war, however it is averted simply because they took the time to talk to each other, and discover the reasons for each others actions! Imagine, had they jumped to conclusions when they saw the altar being built, and sought to avenge the Lord there and then, an extremely bloody battle could have ensued. Instead, they sent a representative from the head of each family to go and talk with the Gadites.
It’s great how the Bible really is current and really does cover the issues of today. I can think back to many occasions where I have jumped to conclusions and acted only to find that I had got the complete wrong end of the stick! By jumping to conclusions and acting upon them, I hurt those very close to me. It may not have been potentially deathly as in Joshua 22, however it still applies as a perfect example.
What can we learn? Don’t jump to conclusions. Many, if not all situations are not as they seem. Reacting quickly to what you think you see can have disastrous affects. Instead, talk with the people concerned, if your fears are grounded then consider, what would Jesus do in this situation? Remember we have no right to judge others, we are called to imitate Christ and be a living witness of His eternal love and grace.
Of course if you then find your fears were fantasy, and you had got the wrong idea, then appreciate the fact that a potentially nasty situation was averted!
