Several years ago when work was scarce, a man seeking a job would come to the door of a shop or factory, only to find a sign upon it, "No help wanted." That door was closed to him. It is not so now. Many shops are in need of help, and the door is wide open for those who wish to work.
Ever since our Lord Jesus died on the cross for our sins the door of heaven has been wide open for any who wish to be saved. He says to you and to me, "I am the Door, by Me if any man enter in he shall be saved" (John 10:99I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture. (John 10:9)). We can only come to God through faith in the Lord Jesus Christ. He alone is the Way. There is no salvation in any other; for, "There is none other name under heaven given among men whereby we must be saved." It is by His precious blood, shed on the cross for sinners, by which we are sheltered from judgment, and find heaven's door wide open.
When God was about to pass through the land of Egypt and destroy all the firstborn sons, He told the Israelites to kill a perfect lamb, and sprinkle its blood outside their doors, on the lintel and door posts. He said, "When I see the blood, I will pass over you, and the plague shall not be upon you to destroy you, when I smite the land of Egypt." Where there was no blood on the door there was no salvation, but where the blood was applied there was safety. So every guilty sinner who has taken refuge under the blood of the Lord Jesus Christ, shed on the cross of Calvary, is safe and sure, for he is inside the door of salvation.
We read of a door in the Ark which God commanded Noah to make to save him and his family from the flood of judgment coming on the whole world for its sins. There was only one door to the Ark. Noah and those who believed God entered into the Ark of Safety, and the Lord shut them in (Gen. 6). They were safe because shut in behind the closed door. All who did not enter into the Ark, which is a picture of the Lord Jesus Christ and His work for us, perished. So will all who now refuse to come to the Lord Jesus and be saved. Judgment is coming on a sinful, guilty world.
"One Door, and only one, and yet its sides are two—
Inside and outside; on which side are you?”
We have a similar picture in the account of the ten virgins in Matt. 25, who went Out to meet the Bridegroom. When He came, "They that were ready went in with Him to the marriage, and the door was shut!" It was too late for the foolish virgins to get in. Only those who were wise got in. The Lord Jesus Christ is coming again. Those who have trusted Him and are wise unto salvation will be with Him when He comes. All others will be left behind for judgment. Then the door of salvation will be closed.
Paul and Silas were in jail because they were Christians (Acts 16). The Lord sent an earthquake and opened the prison doors. The jailer thought his prisoners had fled and was about to kill himself, when Paul cried out, "Do thyself no harm, for we are all here." The jailer fell down before Paul and Silas and asked, "Sirs, what must I do to be saved?" They replied, "Believe on the Lord Jesus Christ and thou shalt be saved; thou and thy house." God's way of salvation for you is the same way: "Believe on the Lord Jesus Christ and thou shalt be saved.”
God now has an open door for salvation; soon it may be a closed door for you, for if you do not enter in you will be outside for judgment. You also have a door which God wishes you to open. It is the door of your heart, which, so far, you have kept closed against God, if you are not a Christian. Jesus says, "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" (Rev. 3:2020Behold, 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)).
"There's a Stranger at the door,
Let Him in;
He has been there oft before,
Let him in.
Let him in ere He is gone,
Let Him in, the Holy One,
Jesus Christ, the Father's Son,
Let Him in!”
Let the Lord Jesus into your heart now, so your sins may be forgiven, ere He go away grieved, and you find, too late, that you a lost soul have closed the door against Him.
