Heb 12:12-17  "Therefore lift your drooping hands and strengthen your weak knees, and make straight paths for your feet, so that what is lame may not be put out of joint but rather be healed.  Strive for peace with everyone, and for the holiness without which no one will see the Lord. See to it that no one fails to obtain the grace of God; that no "root of bitterness" springs up and causes trouble, and by it many become defiled; that no one is sexually immoral or unholy like Esau, who sold his birthright for a single meal. For you know that afterward, when he desired to inherit the blessing, he was rejected, for he found no chance to repent, though he sought it with tears."


There are some clear distinctions between drooping and lifting up, weakness and strength, bitterness and peacefulness, unholiness and holiness, being put out of joint and being healed, being rejected and obtaining the grace of God.
This is a ominous and earnest warning to us. We often hunger to hear of the love of God in terms of acceptance, yet in the Absolute nature of our awesome God we must know that love includes justice and judgment. There is a window now for all of our weaknesses to be strengthened, all of our drooping be lifted, that grace be obtained and the path to holiness be revealed. 
This warning must not go unheeded, don't go past the place of being able to turn to Him. He is Absolute Love.   You come to the same place, the same God that met Moses on the mountain.

Heb 12:18-21  "For you have not come to what may be touched, a blazing fire and darkness and gloom and a tempest and the sound of a trumpet and a voice whose words made the hearers beg that no further messages be spoken to them. For they could not endure the order that was given, "If even a beast touches the mountain, it shall be stoned." Indeed, so terrifying was the sight that Moses said, "I tremble with fear." 


If you really understood the one who you have come to for grace, mercy and forgiveness you would come in trembling and humility. Jesus blood cries out to God as He sits at His Father's right hand, much more than Abel's blood crying out from the ground. Don't think you will escape God's judgment if you reject Jesus!


Heb 12:22-24  "But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering," and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect, and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel. See that you do not refuse him who is speaking. For if they did not escape when they refused him who warned them on earth, much less will we escape if we reject him who warns from heaven." 


This is the time of the ultimate shake up. It is underway. We will either remain or be removed! It is inaugurated by His death and will be consummated by His return!


Hag 2:6,7  "For thus says the LORD of hosts: Yet once more, in a little while, I will shake the heavens and the earth and the sea and the dry land.  And I will shake all nations, so that the treasures of all nations shall come in, and I will fill this house with glory, says the LORD of hosts." 

Mat 27:45-54  "Now from the sixth hour there was darkness over all the land until the ninth hour. And about the ninth hour Jesus cried out with a loud voice, saying, "Eli, Eli, lema sabachthani?" that is, "My God, my God, why have you forsaken me?"  And some of the bystanders, hearing it, said, "This man is calling Elijah."  And one of them at once ran and took a sponge, filled it with sour wine, and put it on a reed and gave it to him to drink.  But the others said, "Wait, let us see whether Elijah will come to save him."  And Jesus cried out again with a loud voice and yielded up his spirit.  And behold, the curtain of the temple was torn in two, from top to bottom. And the earth shook, and the rocks were split.  The tombs also were opened. And many bodies of the saints who had fallen asleep were raised,  and coming out of the tombs after his resurrection they went into the holy city and appeared to many.  When the centurion and those who were with him, keeping watch over Jesus, saw the earthquake and what took place, they were filled with awe and said, "Truly this was the Son of God!" 

There is no level of gratitude, service or worship that can reach or go beyond the level of His power and sacrifice. He is Absolute Love. Let His love consume all that is rebellious and unloving in me. 

Heb 12:26-29  "At that time his voice shook the earth, but now he has promised, "Yet once more I will shake not only the earth but also the heavens."  This phrase, "Yet once more," indicates the removal of things that are shaken--that is, things that have been made--in order that the things that cannot be shaken may remain. "Therefore let us be grateful for receiving a kingdom that cannot be shaken, and thus let us offer to God acceptable worship, with reverence and awe, for our God is a consuming fire."
