Do you truly think that The God who knows all, sees all, and can do all Just because you refuse to admit that He exist is unable to come in a manner that you will see Him come? His capability to do anything is not dependent on anyone’s, never mind yours, acceptance or refusal to accept Him.
Jesus said that He is coming and that you would see Him come. So unless for some reason you die before this event occurs you will have no choice in the matter.
Is it not since that coming is immanent better to be found accepting Him rather than refusing His grace.
