God's irrevocable judgment comes to every soul immediately after death. The ruling or verdict of that judgment will either be eternal life in heaven or eternal damnation in hell, depending on how the soul concerned lived on earth. Consider the following statement made by the Lord Jesus Christ - "And it came to pass, that the beggar died, and was carried by the angels into Abraham's bosom: the rich man also died, and was buried; And in hell he lift up his eyes, being in torments, ..." - Luke 16:22-23.
What does it mean to receive the kingdom of God? It means to receive and believe in the teachings from God's word about His kingdom. These teachings are found in the Bible and are meant to prepare the soul for heaven. However, it is only those that receive the word of God as little children that can make it into heaven. Whereas, believers are commanded to be children in malice, they are commanded to be adults in understanding the things of God.
Unknown to Esther, God planted her in the King's palace for the deliverance of the Jews. And when the time came to play her role, the Lord used her Uncle, Mordecai to sound the alarm. You are not there by accident, but to fulfil destiny. The moment she realised her mission, Esther was determined to fulfil her ministry. She was not afraid to die and boldly declared: if I perish, I perish.
After you have been saved by grace through faith, you must continually prepare for the coming of the Lord, otherwise you cannot make it to heaven. The five foolish virgins did not realise that they did not have enough oil until their lamps went out while waiting for the bridegroom. They were not checking continually to see if they needed to top up. Watch and pray without ceasing as you prepare for the sudden return of the Lord.
Man needs only two things to live - food and the word of God. Your diet is not balanced if all that you depend on for sustenance if food. Your soul and spirit will be famished and you will eventually die of hunger if you fail to feed on the words that come out of the mouth of God. What shall it profit a man, if he shall have enough food and lose his own soul for lack of spiritual nourishment.
