Matthew 7:7-8 tells us to keep knocking: “Knock and the door will be opened to you...and to him who knocks, the door will be opened.”
The word "knock" means to stand at the door and repeatedly rap at it with your knuckles. You knock and wait, then knock again. It might sound a little like this: “I know you are in there,” then you knock again, “I can hear your voice, now come open the door.” Pause for an answer, “I have nowhere else to go and you are the only one who can help me!” Quiet for a second, “If you are on the other side…” You probably know how annoying it can be to listen to someone knock and knock and keep emphatically knocking. If you knock like this, then your desire for entrance must be indeed, very great. In the New Testament, the picture of “open doors” often deals with seeking God’s will and praying for new opportunities to spread the gospel and changing the heart of another person. Let us keep knocking in prayer and may we spread the Good News to anyone that will listen.
