So Jesus said again, "I assure you: I am the door of the sheep. John 10:7
By definition a gate is a way in to something. According to the Bible Jesus is the only way into God’s Holy presence. A few scriptures later we read John 10:9 – I am the door. If anyone enters by me, he will be saved and will go in and out and find pasture. According to this scripture we enter by Jesus the door and go in and out and find pasture. In my words, we go in and out in of life’s experiences in Jesus’ name instead of in our own strength for our own reasons.
I looked up the word gate to help me better understand this scripture. According to a Bible dictionary on line, city gates (especially in the OT) were the center of city life. Important officials are often described as “sitting in the gate.” Gates are in many biblical stories such as the story of Sodom. The elders of cities in OT often sat in or by the city gate, Mordicai learned of plans for the king to be assassinated while sitting in the gate of the city.
Hearers of this verse in John’s gospel most likely would have made the connection of gate for the sheep. Jesus was using the analogy of being a gate to help hearers understand that they had to go through the “Jesus-gate” in the same way that sheep had to go through the “sheep-gate.”
