Noah’s family entered the ark’s door to escape the physical destruction of the flood. God has provided another “door” to save people from the coming eternal judgment.
Jesus Christ said, “I am the door of the sheep” (John 10:7). In that culture the shepherd really was the door to the pen—they would rest in the entryway, ensuring that the sheep would be kept safe. Jesus, the Good Shepherd, is the door through which we must enter to be saved from our sin.
