There are two doors—one open, the other closed. The open door is the door of salvation which is thrown wide open for everyone to enter in—it cannot be more widely opened. It is for "whosoever will" to approach and enter. Christ says, "I am the door: by Me if any man enter in, he shall be saved." John 10:9.
At present it has no bolt, no bar, no lock, and no hindrance. The road to it is clear, the way is plain. Everyone may come. Mercy is now free to all.
But there is another door—a closed one. That is the sinner's heart—barred, bolted and locked. At this door Christ is knocking! "Behold, I stand at the door, and knock." Revelation 3:20. What a picture!
The Savior of sinners is waiting outside entreating to be let in! Now, while Christ is knocking outside your heart, you are the one that must open the door and let Him in.
Christ is willing to come and save you, but on you rests the responsibility of receiving salvation for yourself. Christ does not force His way in. If you refuse to admit Him, the blame of your eternal punishment rests upon you. You have to open your door, or you must bear the future consequences.
Soon the open door will be closed, the Master of the house having shut it. Then, "Too late!" "Too late!" The day of free grace offered to you will then have expired.
Remember, you are either saved or lost. There is no middle ground. You should face that fact at once. Delays are dangerous. Have you received the Lord Jesus Christ as your Savior?
"He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him." John 3:36.
