'Accomplish' in the Bible

For I do not understand my own actions [I am baffled and bewildered by them]. I do not practice what I want to do, but I am doing the very thing I hate [and yielding to my human nature, my worldliness—my sinful capacity].

For Christ is the end of the law [it leads to Him and its purpose is fulfilled in Him], for [granting] righteousness to everyone who believes [in Him as Savior].
