John 10:9

Jesus described Himself as a passageway (cf. John 14:6). His sheep could enter and leave the sheepfold through Him. Obviously the sheepfold here does not refer to Israel as it did previously (John 10:1-5). People could not go in and out of Judaism at will through Jesus. It probably represents the security that God provides, and the pasture outside stands for what sustains their spiritual health and growth. Jesus provides for His people’s security needs and for all of their daily needs 24 hours a day.
