When the kingdom began no amount of appeal based only on friendship or familiarity with Jesus would avail. Jesus had extended fellowship to His hearers and had taught them the way of salvation, but they had rejected His offers. Here Jesus identified the person who shut the door as Himself (cf. Matthew 7:22-23). He will also be the person who will utterly forsake and pronounce judicial rejection on unbelievers for their lack of righteousness (cf. Psalm 6:8). [source][source][source]
