One question at at time 8 apostasy
The Mormons or LDS faith which is The Church of Jesus Christ of Latter Day Saints believes that the true church was organized by Jesus but that it was taken off the earth for a time and later restored through angels restoring revelation, apostles, miracles, the gift of speakng in other langages,prophets, priesthood and many other things.
Matthew 24 verses 23 and 24 speaks of false prophets coming and even deceiving the very elect. Acts 20 Men shall arise speaking perverse things to draw away disciples after them.
II Thessalonians 2 verese 1 to 4 explains that before the Lord comes again there would be a falling away.
1 Timothy 4 verses 1 to 3 says in the latter day some would depart from the truth
II Timothy 4 verses 3 and 4 says that people would not endure sound doctrine
II Peter 2 verses 1 to 3 says false teachers would be among the people
II Peter 3 verses 3 to 7 says that people would walk after their own lusts in the last days.
Isaiah 60 verse 2 says that darkness will cover the earth and the people
Amos 8 verse 11 says the day would come when the Lord God would send a famine of hearing the words of the Lord.
Then in Acts 3 verses 19 to 21 we read that before the second coming of Jesus there would be a restitution or restoration of all things. Revelation 14 verses 6 and 7 says that the gospel would be brought back to the earth by an angel of God.
The foundation of Gods church is first apostles and prophets Ephesians 2 verses 19 and 20
So many people that are against the church use some of the same scriptures to say that the LDS people have been decieved and that they are listening to a different Gospel. Nothing could be farther from the truth. The Gospel is the same gospel that Christ taught.
