Who is knocking on whose door?

It's a wonderful vision that God gave to Emma today during worship, a vision where many people are knocking against this door, but soon many start to give up. In this dry season many are looking for a breakthrough in their lives, in their weariness, in their struggle against sins, in their school work. I guess we all start giving up at some point, when we feel that God dosent care, when we probably feel that we're not worthy for God, when we choose to go back to our vomit and dwell in condemnation. I myself have gone thru this so many times in my short Christian life. But i wonder, who is knocking whose door, really?

i guess many times when we need a breakthru, we begin knocking on God's door, but after awhile when it seems too tiring with the waves of our burdens keep hitting our back, we give up. I gave up many times in my fight against sins, lost hope in the sanctification process and went back feeling condemned. In times of weariness, when quiet time seems so dry and God dosent seem to be speaking, when prayer time was just a little above 5 minutes, I tried pressing in, but after a while i gave up.

Why dosent God answer? Or is He knocking at the doors of our hearts instead?

"Those whom I love I rebuke and discipline. So be earnest, and repent. Here I am! I stand at the door and knock. If anyone hears my voice and opens the door, I will come in and eat with him, and he with Me." Revelations 3:19-20

I thank God that i finally understand this, how i wish i would've understood this earlier, oh i forgot i was busy getting my character up to level so and so. God's been knocking for so long, and calling out to me. "Go and be accountable for your sins", "Go and install a filter on your web browser", "Stop playing computer games and spend more time with Me". When i finally open the door to Him, tada, breakthrough in sins and life. I guess sometimes it's really about letting Him into your life and grant you that breakthru, but before that you've gotta listen carefully and you've gotta unlock your door and turn the knob and let Him in and do His stuff.

Thank God for He is a patient God, He never stops knocking and waiting.
