Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me (Revelation 3:20).
In the following references, we will see that the Holy Spirit, who authored the word of God, loved to use doors as suitable object lessons. I am the door: by me if any man enter in, he shall be saved (John 10:9). This is the door of salvation. Christ is the door; the salvation is eternal. And I give unto them eternal life; and they shall never perish (John 10:28). We must invite Christ through the door of our hearts (above text), so that it would never be said of us, And the door was shut. . . . Verily I say unto you, I know you not (Matthew 25:10,12). Set a watch, O LORD, before my mouth; keep the door of my lips (Psalm 141:3). The door of our lips is the one that gets and keeps most of us in trouble. James mentioned that the tongue can be an unruly evil, full of deadly poison (3:8). To counteract the evil power of the tongue, he instructed us to be swift to hear, slow to speak, slow to wrath (1:19). Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you (Matthew 7:7). This marvelous door of prayer can be opened anytime, anywhere. Behind the closet door (Matthew 6:6) is still one of the greatest places of power and blessing at the Christians disposal. Behold, I have set before thee an open door, and no man can shut it (Revelation 3:8). The door of service is open to all who will enter. Paul said, For a great door and effectual is opened unto me (I Corinthians 16:9). For those who go through Gods open doors, spiritual results are assured. After this I looked, and behold, a door was opened in heaven (Revelation 4:1). Christ will one day say, Come up hither, and all believers in Christ will go through this door of heaven into the very presence of God. May it be today! NPS
