Mguldner,
First, I suggest not meeting with Mormon missionaries alone. Have a strong Christian partner to support you if you wish to meet with them.
Second, you will notice that they speak much of transferring spirits (of course, claiming that it is the “Holy Spirit”). They will want you to invite the spirit, “just to know if what they are saying is true”. The Bible says that we should not believe every spirit, but to test the spirits to see whether they are from God. You will notice that testing of the spirits is always in relation to the truth about Jesus Christ (1 Corinthians 12:3, 1 John 4:1-3, John 16:13-16). A spirit that makes them deny the full deity of Jesus Christ cannot be of God, but is indeed an evil spirit. You do not want to invite an evil spirit; you want to rebuke any such spirit.
Third, in relation to their testimony about Jesus Christ, Mormons do not believe that Jesus is God. They believe that He is “a god”. (They might try to fool you on a bad translation of the Greek, which doesn’t work if you know basic Greek grammar, but may confuse someone who doesn’t know.) As a matter of fact, they believe that there are millions (and possibly more) of gods. They also believe that God the Father did not always have His position as God, but had to achieve deity like YOU need to achieve it! (Oh, and that He also has a physical body) Basically, they believe it is your goal to become your own “god” in your own “kingdom/world/room”, just as God is the ruler of this world. There are many problems with this:
1) The Bible says that apart from the One True God, there is no other god. Isaiah 43:10 says that there has never been any other god before the LORD, nor will there ever be after Him. Isaiah 44:6 says that the LORD is the first and the last, and that apart from Him, there is no other god. (Also see 1 Corinthians 8:4-6)
2) The Bible ascribes deity to Jesus Christ, being the Creator, the Beginning and the End, worshipped, and on and on. (John 1:1-3, Colossians 1:15-17, John 20:28, Revelation 22:12-16, Hebrews 1:6, Matthew 14:33, etc, etc.)
3) This is what Satan used to deceive Eve in the garden of Eden, saying that she would be like God (Genesis 3:5).
4) The ultimate purpose of our existence is to glorify God and to be with Him forever, not to become our own gods in our own separate worlds (Revelation 21:3, Romans 11:36, 2 Corinthians 5:15).
5) The Bible says that God cannot be seen (1 Timothy 6:15-16), and that only Jesus Christ is the God in the flesh (Philippians 2:6-8, Colossians 2:9).
Fourth, they believe that Satan is Jesus’ brother. Okay, you should see that they have a very sympathetic view of Satan by now… As previously mentioned, all things were created by Jesus, whether things on earth or in heaven (that includes Satan; Colossians 1:16).
Jesus = God / Satan = created being
Fifth, they believe that Jesus’ blood makes atonement for a part of salvation, not full salvation. They say that his blood saves people from the temporary state of judgment, not the eternal judgment. They think that heaven and hell are temporary. Therefore, you need to make yourself worthy to become a god, which doesn’t depend on Jesus at all. He just kind of helped you to get out of a temporary impediment… Ouch! This is so wrong, for the following reason:
1) The Bible says that the unrighteous will go to ETERNAL CHASTISEMENT (kolasin aionion), while the righteous will go to ETERNAL LIFE (zoen aionion) – Matthew 25:46). Not temporary.
2) The Bible says that the blood of Jesus cleanses us from all sins, to redeem us and to make us holy (Hebrews 13:12, 1 John 1:7, 1 Peter 1:19).
Sixth, they think that most people will be okay, and that only a few will be in ‘utter darkness’. But this is wrong. Jesus Himself said that most will take the broad way which leads to destruction, while only A FEW will find the narrow way that leads to life (Matthew 7:13-14).
(They will also twist many Scriptures, especially those from 1 Corinthians 15. It would take too long to go through all the possible verses they will twist. However, if you want me to give you more information, just send me an e-mail at plr777@hotmail.com and I will be glad to give you as much preparation as possible.)
By now, you should have plenty to understand the utter heresy of Mormonism. Actually, it is Satanic. But, if you are in Christ, Jesus will keep you safe (1 John 5:18). Also, the Holy Spirit in you is greater than the devil in the world (1 John 4:4). Therefore, if they attack, just look to Jesus for security. Stand firm in Him.
God bless you!
