He has delivered us from the domain of darkness and transferred us to the kingdom of his beloved Son. Note the tense: has delivered, has transferred. This is done. You were not just pulled out of something, you were placed into something.
Your location has changed. You are no longer under the rule of darkness but in the kingdom of the Son. This is not a process you still need to complete, it is accomplished.
When thoughts pull you down as though you still belong to darkness, your mind is playing an old movie. The truth is: You have been transferred. Your place has changed. Clarity starts with accepting that.
