God is Sovereign. He is all powerful, all knowing, all present. He can do whatever He wants, when He wants. And there is no way that we as finite humans could ever take anything from God.
Freewill is something that God has given to mankind. God wants us to love Him and serve Him. But not by force, only out of true love. Because love cannot be forced or manufactured. True love has to be given—it can’t be taken. Think of it this way. If you had a puppy, you want that puppy to love and obey you. You can teach the puppy to obey, but you can’t force their love. That puppy will choose to love you or hate you and there is nothing you can do about it. You may say, “but if God is all powerful, couldn’t he just force our love?” And that is a good question. Think back to our illustration with the puppy. If instead of having a puppy, you were to get a state of the art robotic puppy, it could be programmed to “love” you. And it would automatically obey you. But would it be true love? Absolutely not! It would be programming. God did not program us to Love Him. He gave us the choice to love or hate Him. To Serve or Disobey Him. The purpose being that true love can only come from a free choice.
