There are many examples where Jesus gives specific instructs to His disciples and to all of us that require that we make judgements. Here is one such example. Jesus is giving the disciples specific instructions as he sends them out. Check it out.
Matthew 10:11-15(NKJV)
“Now whatever city or town you enter, inquire who in it is worthy, and stay there till you go out.
And when you go into a household, greet it.
If the household is worthy, let your peace come upon it. But if it is not worthy, let your peace return to you.
And whoever will not receive you nor hear your words, when you depart from that house or city, shake off the dust from your feet.
Assuredly, I say to you, it will be more tolerable for the land of Sodom and Gomorrah in the day of judgment than for that city!
The disciples are
given the task of deciding who is "worthy". Jesus doesn't give them detailed instructions
on how to make that determination. Jesus
trusts that to their judgement.
Imagine that! :)
