What is the purpose of Jesus's church and will his church be partially or fully successful? I believe the purpose of Jesus's church is to bring ALL to God. I also believe that Jesus was telling us that Satan will be unable to prevent Jesus from saving ALL!
In spite of Jesus's statement that Hell will not prevail, mainstream Christianity teaches that Jesus is wrong and that his mission to save all will FAIL.
What do you believe? Do you believe Jesus or do you believe mainstream Christian theology?
We have all been given free will to choose between good and evil and right and wrong. It is taught all through scripture that only those who choose good over evil and repent of their evil ways will make it into the kingdom of heaven. Those who choose evil over good will not be allowed into the kingdom of heaven. This is a basic teaching of Jesus and his disciples. Jesus clearly taught:
Matthew 7:21
21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
Matthew 4:17
17 From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand.
What would be the need of repentance if we all gain entrance into the kingdom of heaven automatically? Jesus obviously requires repentance of those who will enter his kingdom.
Jesus also taught:
Matthew 18:2-3
2 And Jesus called a little child unto him, and set him in the midst of them,
3 And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven.
Here Jesus tells us that unless we become converted and also be humble as a little child, we shall not enter the kingdom of heaven.
It is quite clear from the teachings of Jesus and his apostles that unless we repent and become coverted to his gospel and become faithful and humble as a little child, we will not be allowed to enter the kingdom of heaven.
There are various types of salvation in the Lord's plan. All mankind will be saved from death of the body and be resurrected. Most all will be saved from the lake of fire and brimstone aka outer darkness. Only those who become the sons of perdition will go there. Others will find themselves in lower kingdoms of glory than the kingdom of heaven (see
Doctrine and Covenants 76). Some will be saved from outer darkness and some not. Some will be saved from the telestial kingdom and some not. Some will be saved from the terrestrial kingdom and some not. There are different levels of salvation. Being saved into the highest degree of the kingdom of heaven (aka the celestial kingdom) is the highest degree of Salvation one can obtain. The purpose of Christ's church is to help anyone to gain the highest degree of salvation possible or in other words the highest degree in the kingdom of heaven or celestial kingdom. It is our free will choices that either keep us out of the kingdom of heaven or allow us entrance into the kingdom. It is our choice!
