I started writing something but then decided to let this one stand on what Oswald Chambers said, it’s so thought-provoking for me in my situation today and possibly it will prick your imagination as well. Here are a few snippets I underlined, possibly while reading them you’ll see why I saw trick-or-treaters at God’s door:

The Christian life is not just a handout (perpetual Halloween and Christmas wrapped together), but the privilege of KNOWING God! Going in, sitting down, having a meal–becoming one with Him in life and purpose.
The more you fulfill yourself the less you will seek God.
Experience is a doorway, not a final goal.
…you can never give another person what you have found, but you can cause him to have a desire for it.
” . . . knock, and it will be opened to you” (Luke 11:9). “Draw near to God . . ” (James 4:8). Knock–the door is closed, and your heartbeat races as you knock. “Cleanse your hands . . .” (4:8). Knock a bit louder–you begin to find that you are dirty. ” . . .purify your hearts . . . ” (4:8). It is becoming even more personal–you are desperate and serious now–you will do anything. “Lament . . .” (4:9). Have you ever lamented, expressing your sorrow before God for the condition of your inner life? There is no thread of self-pity left, only the heart-rending difficulty and amazement which comes from seeing what kind of person you really are. “Humble yourselves . . .” (4:10). It is a humbling experience to knock at God’s door–you have to knock with the crucified thief. ” . . .to him who knocks it will be opened.” (Luke 11:10).
I have to ask myself often, “Am I just standing at the door looking for a handout to make life more comfortable–therefore removing my need for God? Or am I truly seeking God with all I’ve got, seeking His will in everything and submitting joyfully to His plans for my life?”
