Computers and electronic devices have a built-in failsafe to ensure that you don’t accidentally delete a file that you intended to keep. When you click on delete, it will not immediately delete the file. Instead, it will ask you, “Are you sure you want to delete this 
file?” When you respond, “Yes,” sometimes it will ask again, “Do you want to permanently delete this file?” Once that file is deleted, it’s gone for good, so you need to be absolutely certain that you want it deleted.
Is there a spiritual application here? Every time a Christian commits a sin, he desperately needs that sin “deleted” from his account. First, he might regret that he did it and want it gone, but that doesn’t delete it. Next, he may resolve that he will never do it again, but that doesn’t delete it. Then, he may reform his habits regarding that sin, but still the sin hasn’t been deleted. Finally, he prays, “Father, I have sinned. Please forgive me” (2 Sam. 12:13; Acts 8:22). Once God knows that you are absolutely certain that you want that sin deleted from your account, He will remove it and never recall it again (Heb. 8:12). It will be permanently deleted!
