Alma 30:41 - 30:45
Alma 30:41 But, behold, I have all things as a testimony that these things are true; and ye also have all things as a testimony unto you that they are true; and will ye deny them? Believest thou that these things are true?
Alma gives his testimony that all things in creation are evidence of the existence of God. The existence of the earth is evidence to Korihor as well but he is saying otherwise. Does Korihor believe that the earth is proof of God’s existence?
Alma 30:42 Behold, I know that thou believest, but thou art possessed with a lying spirit, and ye have put off the Spirit of God that it may have no place in you; but the devil has power over you, and he doth carry you about, working devices that he may destroy the children of God.
Before Korihor can answer, Alma accuses him of really knowing that God does live, but that he is under the influence of satan so much so that the Spirit of God cannot get through to him. Satan is the one pushing him to go about preaching his so called doctrine of every man for himself.
Alma 30:43 And now Korihor said unto Alma: If thou wilt show me a sign, that I may be convinced that there is a God, yea, show unto me that he hath power, and then will I be convinced of the truth of thy words.
Korihor now demands a sign. Unless he is given a sign he will not believe in what Alma is telling him.
Alma 30:44 But Alma said unto him: Thou hast had signs enough; will ye tempt your God? Will ye say, Show unto me a sign, when ye have the testimony of all these thy brethren, and also all the holy prophets? The scriptures are laid before thee, yea, and all things denote there is a God; yea, even the earth, and all things that are upon the face of it, yea, and its motion, yea, and also all the planets which move in their regular form do witness that there is a Supreme Creator.
Alma tells him he has had signs enough. He has the church members, the scriptures, the church leaders as witnesses. The universe itself testifies that there is someone controlling the motion of the planets and stars. Indeed, all the interactions between animal life denote someone is in control.
I guessing that Alma knew about the earth revolving around the sun rather than the sun revolving around the earth as was believed in the days before the renaissance.
Alma 30:45 And yet do ye go about, leading away the hearts of this people, testifying unto them there is no God? And yet will ye deny against all these witnesses? And he said: Yea, I will deny, except ye shall show me a sign.
In spite of these witnesses, Korihor is still going around testifying that there is no God and now is demanding a sign in order to reverse his stance.
