Yea, behold, all the judgments will come upon us which he has testified unto us; for we know he has testified aright unto us concerning our iniquities. And behold they are many, and he knoweth as well all things which shall befall us as he knoweth of our iniquities;
Yea, and behold, if he had not been a prophet he could not have testified concerning those things."
All of us have need to repent. He is a prophet, seer, and revelator, and the words he has spoken are true. We either repent and align ourselves with God's will (as expressed through the words of His prophets) or we don't, and become unprotected, weakened, and alone. If we reject the words of the living prophets we will lose the companionship of the Holy Ghost. And really, what good is life without that?
I for one count it as a miracle that we have living prophets today who are courageous enough to speak the Lord's will even when it is unpopular with the world.
And of course, one of the greatest miracles of all is the Atonement of Jesus Christ. Through Him, we can not only be cleansed from sin, but our very natures can be changed. There is hope for everyone! All it takes is a sincere desire to change (and the willingness to try), and faith in Jesus Christ, and He will help us in ways we can not help ourselves. He can purify us, sanctify us, change us, give us another chance. We can be born again. He does not discriminate against anyone. Everyone has this same opportunity to turn to Him and let Him change you into someone who can enjoy peace, joy, and happiness in this life, and ultimately eternal life.
Everything that seems unfair about life can be made right through the Atonement of Jesus Christ.
