Isaiah 53

    Who has believed what they heard from us? And to whom has the arm of the Lord been revealed?

      For he grew up before him like a young plant, and like a root out of dry ground; he had no form or majesty that we should look at him, and no beauty that we should desire him.

     He was despised and rejected by men; a man of sorrows, and acquainted with grief; and as one from whom men hide their faces he was despised, and we esteemed him not.

     Surely he has borne our griefs and carried our sorrows; yet we esteemed him stricken, smitten by God, and afflicted.

     But he was wounded for our transgressions; he was crushed for our iniquities; upon him was the chastisement that brought us peace, and with his stripes we are healed.

     All we like sheep have gone astray; we have turned every one to his own way; and the Lord has laid on him the iniquity of us all.

     He was oppressed, and he was afflicted, yet he opened not his mouth; like a lamb that is led to the slaughter, and like a sheep that before its shearers is silent, so he opened not his mouth.

     By oppression and judgment he was taken away; and as for his generation, who considered that he was cut off out of the land of the living, stricken for the transgression of my people?

     And they made his grave with the wicked and with a rich man in his death, although he had done no violence, and there was no deceit in his mouth.

     Yet it was the will of the Lord to crush him; he has put him to grief; when his soul makes an offering for sin, he shall see his offspring; he shall prolong his days; the will of the Lord shall prosper in his hand.

     Out of the anguish of his soul he shall see and be satisfied; by his knowledge shall the righteous one, my servant, make many to be accounted righteous, and he shall bear their iniquities.

     Therefore I will divide him a portion with the many, and he shall divide the spoil with the strong, because he poured out his soul to death and was numbered with the transgressors; yet he bore the sin of many, and makes intercession for the transgressors.

“I will strengthen thee” Isaiah 41:10

God has a strong reserve with which to discharge this engagement; for he is able to do all things. Believer, till thou canst drain dry the ocean of omnipotence, till thou canst break into pieces the towering mountains of almighty strength, thou never needest to fear. Think not that the strength of man shall ever be able to overcome the power of God. Whilst the earth’s huge pillars stand, thou hast enough reason to abide firm in thy faith. The same God who directs the earth in its orbit, who feeds the burning furnace of the sun, and trims the lamps of heaven, has promised to supply thee with daily strength. While He is able to uphold the universe, dream not that He will prove unable to fulfill His own promises. Remember what He did in the days of old, in the former generations. Remember how He spake and it was done’ how He commanded, and it stood fast. Shall He that created the world grow weary? He hangeth the world upon nothing; shall he who doth this be unable to support His children? Shall He be unfaithful to His word for want of power? Who is it that restrains the tempest? Doth not He ride upon the wings of the wind, and make the clouds His chariots, and hold the ocean in the hollow of His hand? How can He fail thee? When He has put such a faithful promise as this on record, wilt thou for a moment indulge the thought that He has outpromised Himself, and gone beyond His power to fulfill? Ah, no! Thou canst doubt no longer.

O though who art my God and my strength, 

I can believe that this promise shall be fulfilled,

for the boundless reservoir of Thy grace can never be exhausted,

and the overflowing storehouse of Thy strength can never

be emptied by Thy friends or rifled by Thine enemies.

Isaiah 41:10 

Fear not, for I am with you; 

Be not dismayed, for I am your God. 

I will strengthen you, 

Yes, I will help you, 

I will uphold you with My righteous right hand.

Who is Master?

"I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service."
Romans 12:1 NKJV

The previous appeal to the will (I beseech you) means that the will is to be the master over the body. The thinking of our age says that our body [spirit, soul, flesh, and mind] must tell the will what to do; but the Bible says that our will must bring the body as a living sacrifice to God. The body is a wonderful servant, but a terrible master. Keeping it at God's altar as a living sacrifice keeps the body where it should be.
