who desires all people to be saved and come to full knowledge of the truth.
and to come unto the knowledge of the truth: When one receives the truth, it is then his duty to accept it. God desires that all understand what is required for salvation and that they not be deceived into thinking they are saved when they are not. On the other hand, since God does not save mankind separate and apart from the truth, the question "What is truth?" (John 18:38) is an imperative one to consider. The answer is obvious. Jesus says in prayer to God, "Thy word is truth" (John 17:17). Then again He says, "I am the way, the truth, and the life" (John 14:6). It is the knowledge of that truth, as He had told them earlier, that "shall make you free" (John 8:32). Even though He wills that all men be saved, He does not take away the free moral agency of man to choose his destiny.
