Agood friend of mine was taken one night to see a man who was living a life thatwas on the wild side. While there my friend began to tell him about what theLord could and would do for him. After a very short time that man got up walkedacross the room and opened his front door and asked my friend to leave. As Iwas thinking and remembering about that night on yesterday I had this thoughtthat I would like to share with each of you this morning. That man opened thedoor to let my friend out and my friend got up and left; he walked right outthe front door and went home. If you were to take the word “door” and run itwith your computer you would find that it is mentioned 189 times in the Bible.You will find that the first time it is mentioned is in the fourth chapter ofGenesis and verse seven:  If thou doest well, shalt thou not be accepted? and if thoudoest not well, sin lieth at the door. And unto thee shall be hisdesire, and thou shalt rule over him.
Cain’soffering had been rejected and because of that Cain got angry and disappointed.In the next verse God tells Cain if he was to do well would he not be accepted?On the other hand if you decide not to then sin is lying outside your doorready to attack, for sin wants to control you. Cain decided to allow the sinoutside the door to master him and in the next verse we read of him killing hisbrother.
Genesis4:8  And Cain talked with Abel his brother: and it came to pass,when they were in the field, that Cain rose up against Abel his brother, and slewhim.
Cainallowed sin to master him instead of him mastering sin. In John Chapter 10 andverse nine we read of Jesus saying that He was the door. I am the door: by me if any man enter in, he shall be saved, and shall goin and out, and find pasture. Here we are told of a door that we need toenter. We then read of a door in Revelation chapter three and verse twenty Behold, I stand at the door, and knock: if any man hear myvoice, and open the door, I will come in to him, and will sup with him, and he withme. Here we read of a door that is being knocked on with a voice that issaying open the door for if you do I will come in. This morning we have lookedat three doors one where there is sin just outside that needs to be mastered.Another where Jesus is saying that He was the door and that we can enter in.Then we read of a door that is being knocked on. It is closed and must beopened from the inside and once the door is opened then the visitor which isJesus Christ will come in. In other words Jesus is the door to heaven andhappiness and all you and I have to do is open the door of our hearts and letJesus come in. So that night when my friend was asked to leave with an opendoor he did. We have read of an open door that anyone who will can enter; notleave but enter and if we fail to enter in the results will be awful. Those whohave entered the change will be noticeable.
2Corinthains  5:17  Therefore if any man be in Christ, heis a new creature: old things are passed away; behold, all things arebecome new. Are the old ways of life passing away? Are things becomingnew or is sin just outside the door waiting to masteryou?
