Sometimes what seems like a disunity might actually be a unity in disguise.
Remember when Prophet Jacob p.b.u.h instructed his sons to enter Egypt from different doors (Surah Yusuf: 67). That did not at all result in disunity among them, but rather a strategy, in the sense that if one way turned out to be unsuccessful, the others would have another alternative to get their tasks completed.
It doesn't really matter which way we use then, as long as it leads to the same destination. Each way has its own advantages and disadvantages.
Some people pick a country road for its scenery. Others pick highways because they're faster. But nobody could ever say that their way is better than the other.
Lets just enjoy our road trips and we'll see each other at the destination soon ;)
