Real prophets?

One of the clearest signs of a true prophet of God is that their word ALWAYS comes to pass. This was true of Samuel as a CHILD, yet we are ready to grasp for excuses as adults, while at the same time claiming to be seasoned prophets. Some will argue that we’re under the new covenant, we’re under grace, etc. Why would a BETTER covenant make us WORSE prophets? Grace caused the early church to abound in miracles, but can’t enable prophetic accuracy? The core truth of the inaccurate prophet is they either haven’t learned how to shut up and wait for the leading of the Holy Spirit with regard to what to say, when to say it and whom to say it to, or they are just making stuff up in an effort to impress people and promote their ministry.
