The sixth church is Philadelphia. In the salutation, Jesus reminds them that he is the Messiah, that he is heir to the house of David, and holds the key. And when he applies the key, the door is open, or the door is closed. And no one can change it.
He knows their walk, and what they are doing. They are small, and weak, but he has given them an open door. Their door is open, because they have remained faithful to him. Those who say they follow God, but do not, will submit to this church, because God has given them his love. He will keep them from the effects of judgment.
They have remained faithful, focused on God's mission and God's word. They have prioritized what God sees as important.
The one, who overcomes, will be a pillar in God's house. They will be identified as God's people.
