The only reason we will ever be without an intercessor is because there is no longer any need for intercession. That point in time will occur when every person has made a final decision about the relationship offered them by God and when that relationship has been sealed or rejected. If they choose to reject God's offer to transform their heart in covenant bonds with Him, they are sealed in the service of Satan. Then there is no longer any need or use for an intercessor, for there is no one to intercede with any longer, no one left to enter into a relationship different than the one they have chosen.
Yes, truth is lacking; And he who turns aside from evil makes himself a prey. Now the LORD saw, And it was displeasing in His sight that there was no justice. And He saw that there was no man, And was astonished that there was no one to intercede; Then His own arm brought salvation to Him, And His righteousness upheld Him. He put on righteousness like a breastplate, And a helmet of salvation on His head; And He put on garments of vengeance for clothing And wrapped Himself with zeal as a mantle. (Isaiah 59:15-17)
As long as there are individuals who have not finalized their choice of which master to render their loyalty and service to, Jesus will continue to intercede with them, seeking to draw them in by any means possible to the side of truth and loyalty to the God of heaven. But there does come a time when people have so hardened their hearts that it is no longer possible whatsoever for them to change their minds. At this point they have destroyed their capacity and ability to choose differently by repeated rejections of the voice of the Holy Spirit. At this time God respects that choice by letting them have the consequences of their own persistent demands. He gives them over – which is the Bible's definition of the wrath of God. (Romans 2:24, 26, 28)
As for you, do not pray for this people, and do not lift up cry or prayer for them, and do not intercede with Me; for I do not hear you. Do you not see what they are doing in the cities of Judah and in the streets of Jerusalem? The children gather wood, and the fathers kindle the fire, and the women knead dough to make cakes for the queen of heaven; and they pour out drink offerings to other gods in order to spite Me. (Jeremiah 7:16-18)
When an intercessor pleads for God to show mercy to those who have completely rejected His mercy, that is an attempt to get God to reverse His decision to respect their final choice in regards to His offers of mercy and grace. There is no point in God continuing to offer mercy and forgiveness to those who have destroyed all their ability to accept it. The only thing left is to release them to their choices.
Some are confused when they read that everyone will bow in willing worship before God. They assume that because everyone will worship that must mean they will be saved as well. But the two are not the same thing.
For this reason also, God highly exalted Him, and bestowed on Him the name which is above every name, so that at the name of Jesus EVERY KNEE WILL BOW, of those who are in heaven and on earth and under the earth, and that every tongue will confess that Jesus Christ is Lord, to the glory of God the Father. (Philippians 2:9-11)
At the same time, many take this to believe that because every knee will bow that God will resort to the use of force in the end to get unrepentant sinners to worship Him. But that is equally false because it pictures God as one willing to stoop to the methods of His arch-enemy to accomplish securing worship for Himself. This idea is reflective of the spirit of Satan, not that of our wise, loving heavenly Father. This is something that many of us think is only logical because we cannot perceive of any other way that this could be accomplished. But our own ignorance should not be the basis for our beliefs about God's character.
God values freedom more than anything else. This is because true love can only thrive in an atmosphere free of all coercion. So it simply would be illogical and counter-productive for God to resort to removing people's freedom in order to secure worship for Himself. That is a demonstration of selfishness, not the Spirit of selfless love and compassion that marks the acts of God. It is crucial that we clear away the clouds of deception and lies that still fog our vision so that we can see the real truth about the way God relates to sinners. When that begins to take place it will become much easier for us to perceive the real truth and the motivation that will finally cause everyone, both saved and lost alike, to bow before God in willing worship and acquiescence without any coercion whatsoever.
But while all will be in full agreement that God is absolutely fair in every respect and that He is just in the way He has chosen to resolve the problems that sin brought into the universe, it does not follow that all will then be ready to surrender to His authority or be able to thrive in His presence. In fact, ironically it is their very act of willing worship and recognition of His total lack of coercion that plunges the lost into the emotional agonies described as the fires of hell. For to stand in the presence of anyone who loves you so purely and passionately and has endured your rejection of their advances without the slightest trace of evil or resentment or hostility is to self-induce an emotional torment that is on a scale equal with or more intense than the worst possible torture anyone could inflict on you from the outside. This is the true condition that creates the torments of hell.
He who overcomes will thus be clothed in white garments; and I will not erase his name from the book of life, and I will confess his name before My Father and before His angels. (Revelation 3:5)
Jesus is currently our intercessor and friend. But that is not for the purpose of changing God's heart about us but to change our hearts about God. When we overcome the lies about God in our hearts and minds through the intercession of Jesus on His behalf, then Jesus, God and ourselves will be in perfect agreement. And the true meaning of the word confess simply means to agree.
And that is the final goal of everything the Godhead and all of heaven has been trying to achieve all throughout this long trial and controversy with Satan's rebellion. God wants to restore fully the atmosphere of full agreement without resorting to any of Satan's false techniques of force, deception or fear. God will finally win this war and He is going to be vindicated using only the truth and the methods consistent with both truth and unfailing love. It is love that is going to overcome in the end, not fear, not force, not deception.
Love is patient, love is kind and is not jealous; love does not brag and is not arrogant, does not act unbecomingly; it does not seek its own, is not provoked, does not take into account a wrong suffered, does not rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, endures all things. Love never fails...
For now we see in a mirror dimly, but then face to face; now I know in part, but then I will know fully just as I also have been fully known. But now faith, hope, love, abide these three; but the greatest of these is love. (1 Corinthians 13:4-8, 12-13)
