everyone who calls on the name of the LORD will be saved: Calling on God's name should not be a final act of desperation. It should be part of a lifelong commitment to worship, serve, and have fellowship with the Lord (see Genesis 12:8; Psalm 105:1; Isaiah 12:4; Romans 10:13; 12:1–2).
Those whom the Lord has called are his chosen remnant. They are the survivors of judgment who worship him (see 2 Kings 19:31; Ezra 9:8–15; Isaiah 10:20–22).
