Another earthquake in the world yesterday, this time in the eastern U.S., 6.0 on the Richter Scale, happily, with no deaths. Any tremor, and I’ve felt several there and here, reminds us that the earth isn’t exactly terra firma (in Portuguese, that would be terra firme).
However, God’s solid foundation remains standing, bearing this seal: “The Lord knows those who are his,” and “Everyone who confesses the name of the Lord must turn away from evil.”
2 Timothy 2:19 NET
False doctrine will not be successful. It will not shake God’s foundation. It will not convince those who belong to the Lord, because they have abandoned the sin of such teaching.
The sayings written on the foundation indicate its nature, its firm quality, by God’s action of sealing the foundation. He it is who keeps it standing. He guarantees its authenticity by the seal, and affirms his ownership over it.
One commentator says that, by the Old Testament quotations in this verse, the foundation refers metaphorically to the church. As in Numbers (source of the first quote), “the people must choose sides, thereby establishing their identity.” (Philip H. Towner, The letters to Timothy and Titus NICNT [Eerdmans, 2006]: 536-38)
