Mark 4:11 says, “And he (Jesus) said unto them, Unto you it is given to know the mystery of the kingdom of God: but unto them that are without, all these things are done in parables.” The Kingdom of God was a mystery. A Biblical “mystery”, was a divine purpose, which God kept hidden in times past, but has now disclosed or revealed. Now, we know the Jews knew about the Kingdom of God, because it was often mentioned in the Old Testament. So, why did Jesus say the Kingdom of God was a mystery? Let’s get into God’s Word.
The mystery of the Kingdom of God, was that it had come without observation (Lk 17:20-21). Jesus brought it. The Kingdom was in their midst. The Kingdom would be within those who would accept it. To the Jews, this was a completely foreign idea of what the Kingdom of God was. They saw only the physical aspect of it. What we know to be the second coming of Christ, they think to be the first coming of Messiah.
Messiah would be a mighty, conquering King, who would tread underfoot all the enemies of God. He would rule with a rod of iron. The earth would have peace and rest. The wolf would lie down with the lamb (Isa 11:6-8). The nations would beat their weapons into farm equipment (Isa 2:4). That sounds like the second coming and millennial reign of Christ.
However, when Jesus came the first time, He didn’t come in that way. He came quietly, secretly; humbly - without observation (to most). He came as the Lamb of God the first time. He’ll come as the Lion of the Tribe of Judah the second time. He came to give Himself as a sacrifice for our sins the first time. He will come the second time, to take His rightful place on the throne of David and reign sovereign for a thousand years.
John the Baptist even had some doubts, because Jesus wasn’t taking His place as King; like they believed He would based on the Scriptures (Lk 7:19-28). This was the mystery of the Kingdom. It came quietly. It didn’t do away with the present evil age; it came while this present evil age is still in existence. Men must enter into this invisible Kingdom now, in order to enter into the visible Kingdom to come.
However, in this current age, the Kingdom comes with persuasion, and not compulsion. Our commission is to plead with men to be reconciled to God (2Cor 5:19-20), but we are in no way, shape, or form, to try and make people receive Jesus. Compulsion is the method of some other religions, such as Islam (which means submission) - not Christianity. We simply sow seed (speak the Word of God) - Mt 13:3-9. People can accept it or reject it. That’s not our problem or responsibility. God won’t violate our free will and make anyone get saved; why would we try to?
The Kingdom of God has come secretly. It exists now on this earth, but it is not manifested the way it will be at the second coming of Christ. We can taste the powers of it now, but not the fullness of it. The enemies of God have not been vanquished; Satan, sin, and evil still operate in this world. Yet a stronger has come and bound the strong man and has delegated His strength to us who believe. Jesus has given us His authority to exercises on this earth until He returns. We need to use it (Jam 4:7).
Just speak truth. Don’t try and force someone to say the “sinner’s prayer.” If it isn’t said from a repentant and yielded heart, it doesn’t mean a thing anyway. We must enter the Kingdom of God now - in this life (2Cor 6:1-2) - if we are to enter it in the age to come. Only those who have the Kingdom within them now, will be within the Kingdom then. Unless one is born again - born of water and of Spirit - they will not see the Kingdom now (Jn 3:3), nor will they enter the Kingdom then (Jn 3:5).
Are you presently in the Kingdom of God? Have you repented, which means you have turned from darkness to light, and from the authority of Satan to God (Act 26:18)? Have you truly been born again by water and Spirit, believing with all your heart Jesus is risen from the dead, and confessing Him as Lord (King) and Savior (Rom 10:9-10)? You must do so now, or forfeit any part in the Kingdom to come. That is the Word of The Lord. The choice is yours. To Jesus The King be all worship and honor and glory forever and ever. Amen.
