Alma 30:36 - 30:40
Alma 30:36 And Korihor answered him, Yea.
Korihor said that Alma was purposely trying to deceive the people for his own gain. Alma was not really interested in the people enjoying the joy that comes from gospel living.
Alma 30:37 And then Alma said unto him: Believest thou that there is a God?
Alma then asks him if he believed in God?
Alma 30:38 And he answered, Nay.
Korihor said no.
Alma 30:39 Now Alma said unto him: Will ye deny again that there is a God, and also deny the Christ? For behold, I say unto you, I know there is a God, and also that Christ shall come.
Alma gives testimony that he knows that there is a God and that Christ will come. He asks Korihor again if he will deny both God and Christ?
Alma 30:40 And now what evidence have ye that there is no God, or that Christ cometh not? I say unto you that ye have none, save it be your word only.
Alma asks Korihor what evidence does he have to prove there is no God or that Christ will not come? The fact is that Korihor has none, only his word.
It is difficult to prove a negative so Korihor could not prove his contention. But what is significant in Alma's words is that it is only his opinion. If you look very carefully at the so called certainties preached by men of this world they are all just opinions. The doctrine of the trinity is only the opinion of a group of men. Interpretations of scripture by men are all opinions. Only those inspired by the Holy Ghost can give certainty.
