This is one rare case in which I agree with Davo, that “Jesus was NOT talking about who does or doesn’t get into heaven postmortem.” One of the most enlightening passages concerning the Kingdom of God is found in the words that Jesus spoke to the Pharisees:
Being asked by the Pharisees when the kingdom of God would come, he answered them, “The kingdom of God is not coming in ways that can be observed, nor will they say, ‘Look, here it is!’ or ‘There!’ for behold, the kingdom of God is in the midst of you.” (Luke 17:20,21 ESV)
The Kingdom of God IS (present tense) right in the midst of you Pharisees, so how can you ask when it is coming? A kingdom consists of a king and his subjects. Jesus is the King, and His disciples are His subjects.
Thus Jesus and His disciples comprised the Kingdom of God at that time—the Kingdom in its infant stage.
Jesus gave parables about the Kingdom in its infant stage, parables about its growth, and parables about its final stage Very little is said in the NT about heaven as a dwelling place for the saints post-mortem.
We’ve all heard about the “mansions” in heaven that Jesus has gone to prepare for us. (John 14:2,3). Jesus hasn’t returned yet; is He still busy preparing a luxurious mansion for each one of us?
In My Father’s house are many mansions; if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again and receive you to Myself; that where I am, there you may be also. (NKJV)
The first thing of which we should be aware is that the word that the NKJV translates as “mansions” should be translated as “dwelling places.” Oh, “mansions” was all right in the 1600s, for the word MEANT “dwelling places” at that time. When you read Jesus words here in context it becomes plain that Jesus was going to prepare His Body, the Assembly (later called “the Church”) where there would be places for each of his disciples to occupy a special dwelling place for himself. And that Assembly came into being on that special day of Pentecost of which we read in Acts 2.
