A:One way in which Matthew's Gospel is unique is in its frequent references to the 'kingdom of heaven'. One would indeed expect that Matthew listened to Jesus preaching the kingdom of heaven. Mark's Gospel and Luke's Gospel frequently mentions Jesus talking of the 'kingdom of God', but not the kingdom of heaven, but not the kingdom of heaven. John makes just two references to the kingdom of God. Scholars say that the disciple Matthew did not write the Gospel that now bears his name, in fact they say that the Gospel could not even have been written by an eyewitness to the life and mission of Jesus. It is significant that all the New Testament Gospels were originally anonymous and only attributed by the Church Fathers to the apostles whose names they now bear, later in the second century.When read in the original Greek, it is clear that there is a literary dependency among the Gospels of Matthew, Mark and Luke, with a less obvious dependency in the case of John's Gospel. Many passages in the synoptic gospels are actually identical in the Greek language. Because of this, the Church Fathers decided that Matthew was written first, and that Mark and Lukewere written as copies of Matthew. However, it is clear that the author of Luke was unaware of Matthew. Moreover, scholars have demonstrated that Matthew and Luke must have been based on Mark, with both authors also relying on the hypothetical 'Q' document for further sayings attributed to Jesus, as well as providing, in each case, other material unique to that Gospel. Anyone who had known Jesus would not have had to rely so heavily on Mark and Q.We can therefore say that 'Matthew', the author of Matthew's Gospel did not hear Jesus preach anything, whether about the kingdom of heaven or otherwise.
The verse you are referring to is in Matthew 16:19, which reads "And I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven."
The phrase "kingdom of heaven" is unique to Matthew's gospel, appearing nowhere else in the Bible. Of its 32 appearances, thrity-one times it is spoken by Jesus; once by the disciples.
Baptism is the normal way to enter the Kingdom of God but there are other ways to the Kingdom of Heaven also known as the Kingdom of God e.g. 'Let the children come to me, do not hinder them; for to such belongs the kingdom of God. Truly, I say to you, whoever does not receive the kingdom of God like a child shall not enter it.'." (Mark 10). "Not everyone who says to me 'Lord, Lord' shall enter the kingdom of heaven, but he who does the will of my Father who is in heaven" (Matthew Ch 7) "Blessed are those who are persecuted for righteousness' sake, for theirs is the kingdom of heaven. ….." (Matthew Ch 5) "I tell you, many will come from east and west and sit at table with Abraham, Isaac, and Jacob in the kingdom of heaven, while the sons of the kingdom will be thrown into the outer darkness; there men will weep and gnash their teeth." (Matthew Ch 8) "He that believeth and is baptized shall be saved; but he that believeth not shall be damned" (Mark xvi, 16). But they will enter the Kingdom of their own God.
In Matthew 13 there are six parables of the kingdom of heaven that Jesus told; which is a good place to start reading of the many stories of Jesus
In Matthew 13:11-12, Jesus explains that those who seek to understand the teachings of the kingdom of heaven will be given more knowledge, while those who do not seek understanding will lose even the little knowledge they have. This emphasizes the importance of actively seeking spiritual understanding and growth in order to comprehend the mysteries of the kingdom of heaven. It suggests that a receptive and seeking heart is necessary to grasp the deeper truths of God's kingdom.
Matthew 7:21New King James Version (NKJV) I Never Knew You21 "Not everyone who says to Me, 'Lord, Lord,' shall enter the kingdom of heaven, but he who does the will of My Father in heaven.
Jesus says to St. Peter--19 "I will give you the keys of the kingdom of heaven; and whatever you bind on earth shall have been bound in heaven, and whatever you loose on earth shall have been loosed in heaven." --Matthew 16:19 New American Standard Bible
Here are a few illustrations.Reading in Matthew 13:24-30(CEB), Jesus said:"The kingdom of heaven is like someone who planted good seed in his field...""The kingdom of heaven is like a mustard seed...planted in his field..""The kingdom of heaven is like yeast...hid in a bushel of wheat flour...""The kingdom of heaven is like a treasure that somebody hid in a field...""The kingdom of heaven is like a merchant in search of fine pearls...""The kingdom of heaven is like a net that people threw into the lake..."
The answer to this question is not as simple as it seems. The Kingdom of Heaven is the only route to Heaven and eternal life in God the Father. It is only the unbaptised who lead an evil life who are excluded from the Kingdom of Heaven. All baptised persons enter the Kingdom of Heaven along with those who carry with them the innocence of childhood, those do God's will etc.This does not mean that all who enter the Kingdom of Heaven will eventually attain eternal life in God the Father. It should be noted that the Kingdom of Heaven will be delivered to God the Father on the Last Day when the good and the bad in the Kingdom of Heaven will be separated. "…Then the righteous will shine like the sun in the kingdom of their Father." (Matthew Ch 13).AnswerI think it is that if you do sin, and you do not repent or ask God to help you truly repent, that will keep you out of Heaven. If you do not fully accept Jesus and God into your heart, that will keep you out of Heaven.What, do you want to go to Hell?
In the Church of Jesus Christ of Latter-day Saints (the "Mormon" church) a kingdom could refer to a couple things.First is the Kingdom of God. If someone references 'building the kingdom' or something similar, they are referring to the Kingdom of God. The Bible Dictionary, published by the Church, puts it this way, "Generally speaking, the the kingdom of God on the earth is the Church. It is a preparation for the greater kingdom-the celestial or kingdom of heaven. However, kingdom of heaven is sometimes used in scripture to mean the Church, meaning that the true church on the earth is the path to heaven, and is the kingdom of heaven on earth."Second, the Kingdoms of Glory. Mormons believe that within heaven there are three 'kingdoms' or degrees. The highest of these is the Celestial Kingdom, followed by the Terrestrial and Telestial Kingdoms. There are different requirements to be admitted into each kingdom. You can learn about the kingdoms of glory at the "Related Link" below, it's too much to include here.
