A yoke is something that is a burden. Works based grace is a burden as no one could or can do anything to receive God's grace. From Adam, it has been offered to all mankind freely but whether or not we receive the blessings and the rewards that comes from His grace is up to us. By that rationale, "by grace are ye saved through works of faith," "by works of righteousness which we have done." (contra Eph. 2:8,9; Titus 3:5) God does reward faith, (Heb. 10:35) and which must have works if genuine,as works justify one as having faith, but it is faith that is counted for righteousness, (Rm. 4:4-6ff) and then shows itself in works.
However, according to the implications of your soteriology, one must be circumcised and keep all the law, which is what Acts 15 and other texts counters.
I did not say as you are suggesting. And what is the hangup with circumcision? Timothy was circumcised by Paul and Titus was not. Why? Because their situations were different. One, Timothy did it our of love and obedience as He was entering God's shepherd-ship and Titus stood firm in that circumcision is not a requirement for receiving the free gift. One can pluck any verse and make it what they want without considering the surrounding text around it and that is what Christendom has done, plucked to make doctrine that fits their fleshly desires. But with that said, as I have said before, our works is evidence of our faith, our belief as one is steered to do and act out that which they believe and that is work manifested is our fruit. Just as it was for Abraham, our father.
Jas 2:17 So also belief, if it does not have works, is in itself dead. 18 But someone might say, “You have belief, and I have works.” Show me your belief without your works, and I shall show you my belief by my works. 19 You believe that Elohim is one. You do well. The demons also believe – and shudder! 20 But do you wish to know, O foolish man, that the belief without the works is dead? 21 Was not Abraham our father declared right by works when he offered Isaac his son on the altar? 22 Do you see that the belief was working with his works, and by the works the belief was perfected? 23 And the Scripture was filled which says, “Abraham believed Elohim, and it was reckoned to him for righteousness.” And he was called, “Elohim’s friend.” 24 You see, then, that a man is declared right by works, and not by belief alone. ... 26 For as the body without the spirit is dead, so also the belief is dead without the works.
