While ACIM does not always use every single word in the English language, it does nevertheless speak of various topics in various ways. The meaning of the words is deeper than the words.
Here are some statements about surrendering the ego, even though "surrender" as a word never appears.
"You are not the victim of the world you see because you invented it. You can give it up as easily as you made it up."
"If you want peace, you must give up the idea of conflict entirely."
"Be willing to give up the goals you have established for everything."
"The Holy Spirit guides you into life eternal, but you must relinquish your investment in death, or you will not see life though it is all around you."
"The sick are healed as you let go of all thoughts of sickness, and the dead are raised when you let thoughts of life replace all thoughts you ever held of death."
"You cannot really not let go what has already gone."
"I can escape from the world I see by giving up attack thoughts."
"It is crucial to your learning to be willing to give up the goals you have established for everything. The recognition that they are meaningless, rather than "good" or "bad," is the only way to accomplish this. "
"He can learn this only as he actually does give up the valueless."
"What you give up is merely the illusion of protecting illusions."
"I can give up but what was never real"

"And He Himself will place a spark of truth within your mind wherever you give up a false belief, a dark illusion of your own reality and what love means."
" I would give up my insane wishes and walk into the sunlight"
"But the experience of freedom and of peace that comes as you give up your tight control of what you see speaks for itself."
"Where all reality has been withdrawn from what was never true, can it be hard to give it up, and choose what must be true"
"Give up this frantic and insane attempt that cheats you of the joy of living with your God and Father, and of waking gladly to His Love and Holiness that join together as the truth in you, making you one with Him."

"It has never really entered your mind to give up every idea you ever had that opposes knowledge."
"You are not the victim of the world you see because you invented it. You can give it up as easily as you made it up."
"Guidance is evaluative, because it implies there is a right way and also a wrong way, one to be chosen and the other to be avoided. 3 By choosing one you give up the other"
When you accept a brother's guiltlessness, you will SEE Atonement in him. For, by proclaiming it in HIM, you make it YOURS, and you WILL see what you sought. You will not see the symbol of your brother's guiltlessness shining within him, while you still believe IT IS NOT THERE. HIS guiltlessness is YOUR Atonement. Grant it to him, and you will see the truth of what you have acknowledged. Yet truth is offered FIRST, to be received, even as God gave it first to His Son. The first in time means nothing, but the First in Eternity is God the Father, Who is both First and One. Beyond the First, there is no other, for there is no order, no second or third, and nothing BUT the First.
You who belong to the First Cause, created by Him like unto Himself, and part of Him, are more than merely guiltless. The state of guiltlessness is only the condition in which what is NOT there has been REMOVED, from the disordered mind that THOUGHT it WAS. This state, and only this, must YOU attain with God beside you. For until you do, you will still think that you are separate FROM Him. You can feel His Presence NEXT TO you, but CANNOT know that you are one with Him. This need not be taught. Learning applies ONLY to the condition IN WHICH IT HAPPENS of itself.
When you have let all that has obscured the truth in your most holy mind be undone for you, and stand in grace before your Father, He will give Himself to you, as He has ALWAYS done. Giving Himself is all He knows, and so it is ALL knowledge. For what He knows NOT cannot be, and therefore CANNOT BE GIVEN. Ask not to BE forgiven, for this has already been accomplished. Ask rather to LEARN how to forgive, and restore WHAT ALWAYS WAS to your unforgiving mind. Atonement becomes real and visible, to them that USE it. On earth, it is your ONLY function, and you must learn that it is all you WANT to learn.
You WILL feel guilty 'til you learn this. For, in the end, whatever form it takes, your guilt arises from your failure to fulfill your function in God's Mind with ALL OF YOURS. Can you ESCAPE this guilt, by failing to fulfill your function HERE? You need not understand creation, to do what must be done, BEFORE that knowledge would be meaningful to you. God breaks no barriers; neither did He MAKE them. When YOU release them, they are gone. God will not fail, nor ever has, in anything.
Decide that God is right, and YOU are wrong, about yourself. He created you out of Himself, but still WITHIN Him. He knows what you are. Remember that there is no second to Him. There cannot, therefore, be anyone WITHOUT His Holiness, nor anyone unworthy of His perfect love. Fail not in your function of loving in a loveless place, made out of darkness and deceit, for thus are darkness and deception UNdone. FAIL NOT YOURSELF, but instead, offer to God AND YOU His blameless Son. For this small gift of appreciation FOR His love, God will Himself exchange your gift for HIS.
Before you make ANY decisions for yourself, remember that YOU HAVE DECIDED AGAINST YOUR FUNCTION IN HEAVEN, and consider carefully whether you WANT to make decisions here. Your function here is only to decide AGAINST deciding what you want, in recognition that YOU DO NOT KNOW. How, then, CAN you decide what you should do? Leave ALL decisions to the One Who speaks for God, and for your function as He KNOWS it. So will He teach you to remove the awful burden you have laid upon yourself, by loving not the Son of God, and trying to teach him guilt INSTEAD of love. Give up this frantic and insane attempt, which cheats you of the joy of living with your God and Father, and awaking gladly to His Love and Holiness, which join together as truth in YOU, making you One with Him.
When you have learned how to decide WITH God, ALL decisions become as easy and as right as breathing. There is no effort, and you will be led as gently, as if you were being carried along a quiet path in summer. Only your own volition seems to make deciding hard. The Holy Spirit will not delay at all in answering your EVERY question what to do. He KNOWS. And He will TELL you, and then do it FOR you. You who are tired might consider whether this is not more restful than sleep. For you can bring your guilt into sleeping, but NOT into this.
