"I 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
Jesus, the great I AM, is the entrance into the true church, and  the way of access to God Himself. He gives to the man who comes to God by Him  four choice privileges.
1. He shall be saved. The fugitive manslayer passed the  gate of the city of refuge, and was safe. Noah entered the door of the ark, and  was secure. None can be lost who take Jesus as the door of faith to their souls.  Entrance through Jesus into peace is the guarantee of entrance by the same door  into heaven. Jesus is the only door, an open door, a wide door, a safe door; and  blessed is he who rests all his hope of admission to glory upon the crucified  Redeemer.
2. He shall go in. He shall be privileged to go in  among the divine family, sharing the children's bread, and participating in all  their honours and enjoyments. He shall go in to the chambers of communion, to  the banquets of love, to the treasures of the covenant, to the storehouses of  the promises. He shall go in unto the King of kings in the power of the Holy  Spirit, and the secret of the Lord shall be with him.
3. He shall go out. This blessing is much forgotten. We  go out into the world to labour and suffer, but what a mercy to go in the name  and power of Jesus! We are called to bear witness to the truth, to cheer the  disconsolate, to warn the careless, to win souls, and to glorify God; and as the  angel said to Gideon, "Go in this thy might," even thus the Lord would have us  proceed as His messengers in His name and strength.
4. He shall find pasture. He who knows Jesus shall  never want. Going in and out shall be alike helpful to him: in fellowship with  God he shall grow, and in watering others he shall be watered. Having made Jesus  his all, he shall find all in Jesus. His soul shall be as a watered garden, and  as a well of water whose waters fail not.  Evan.Dr.Sanjay
