Julius Caesar was clearly one of the most colorful figures of ancient history.
His military exploits and unrivalled oratory powers have placed his name firmly in the annals of world history. Born with unbridled political ambition and unsurpassed oratory skills, Julius Caesar manipulated his way to the position of consul of Rome in 59 BC. After his year of service he was named the governor of Gaul (north of Italy) where he amassed a personal fortune and exhibited his outstanding military skill in subduing native Celtic and Germanic tribes.

Caesar’s popularity with the people soared, presenting a threat to the power of the Senate and to Pompey, the Roman general who held power in Rome. Accordingly, the Senate called upon Caesar to resign his command and disband his army or risk being declared an “Enemy of the State”. Pompey was entrusted with enforcing this edict – the foundation for civil war was laid.

In January 49 BC, Caeser was staying in the northern Italian city of Ravenna and he had a decision to make. Either he acquiesced to the Senate’s demand or he moved southward to confront Pompey and plunge the Roman Republic into a bloody civil war.

A crucial geographical point figured in his decision: the Rubicon, a shallow river which marked the boundary between Gaul and Italy. An ancient Roman law forbade any general from crossing the Rubicon River and entering Italy proper with a standing army. To do so was treason.

This tiny river would reveal Caesar’s intentions and mark the point of no return. Once he crossed, there would be no turning back. It became an irrevocable decision.
Coming up with his troops on the banks of the Rubicon, which was the frontier of his province, he halted for a while, and considering in his mind the importance of the step, he meditated and turned to those about him, saying: ‘Still we can retreat! But once we pass this little bridge, and nothing is left but to fight it out with arms!’

Suetonius, a Roman historian, records that after some hesitation, Julius Caesar issued the command, “Advance!” When on the southern side, he shouted, “The die is now cast.”

These words have echoed accross several centuries, becoming proverbial for decisions, which, once made, cannot be reversed; in some case, not at all.

Dear reader, do you realize that there are a number of decisions in this life which are irreversible, and sometimes with eternal consequences?

Do you realize that there are several “Rubicons” which we must decide whether to cross or not?

Jeremiah 6:16 says: Thus saith the LORD, Stand ye in the ways, and see, and ask for the old paths, where is the good way, and walk therein, and ye shall find rest for your souls. But they said, we will not walk therein.”

It is possible to live on earth without giving serious consideration to the consequences of certain decisions or actions we take. The above Scripture cautions against making a hasty decision as to which of many “ways” to be followed, hence the caution to stand, see and ask before making a decision.

Many a time, certain decisions we make do not bear any weighty consequence. However, certain decisions are gravitational and present” Rubicon” situations before us. While several example maybe cited, there is no decision as crucial as the question of what will happen to me after life.

There are those who labour under the illusion that they may neglect the salvation of their souls in this life (Hebrews 2:3), and yet somehow they believe that in the world-to-come pardon will be bestowed. All forms of false religions abound with promise of eternal bliss at the end of a Christ-less life. Some even teach that through reincarnation people will have the opportunity of living earthly lives all over again with various avenues of development.

This is not only contrary to the Scripture, it is a satanic trap to lead you down the dreary road of hell.
“it is appointed to man once to die, and after this judgment.” (Hebrews 9:27).
No purgatory, no re-incarnation. Just like a broken egg cannot be re-gathered, so also live can only be lived once.

Human history is divided between time and eternity. What you do in time determines your placement and standing in eternity. Once life comes to a close on this side, no further decision can be made anymore. All avenues for repentance are closed and only judgment awaits such a person.

Friend, have you placed your faith in the Son of God or are you waiting till the hour of death to do so? In His story of the rich man and Lazarus, Jesus unquestionably taught that once a person dies there is no further opportunity for preparation (Luke 16:19).

When a person’s eyes close in death, he has crossed his “final Rubicon” and there is no turning back. Like Julius Caesar, the die is cast at that moment.

Choices are so important in life, and how tragically neglectful we are on occasion in not facing and giving serious consideration to the gravity of these matters. Some foolish decisions cannot be washed away with an ocean of tears. (Hebrews 12:15-17)

Dear friend, do not postpone the decision. Now is the time to decide for Christ. Will you reject the Spirit’s call to your heart at this moment? No excuse would do.

A song writer says:

There’s a line that is drawn by rejecting our Lord,
Where the call of His Spirit is lost,
And you hurry along with the pleasure-mad-throng-
Have you counted, have you counted the cost?
Chorus:
Have you counted the cost, if your soul should be lost,
Tho’ you gain the whole world for your own?
Even now it may be that the line you have crossed,
Have you counted, have you counted the cost?
You may barter your hope of eternity’s morn,
For a moment of joy at the most,
For the glitter of sin and the things it may win-
Have you counted, have you counted the cost?
While the door of His mercy is open to you,
Ere the depth of His love you exhaust,
Won’t you come and be healed, won’t you whisper, I yield-
I have counted, I have counted the cost.
