The god of this age has blinded the minds of unbelievers so they cannot see the light of the gospel of the glory of Christ, who is the image of God. — 2 Corinthians 4:4

The cup of salvation — what a phrase. The psalmist takes it and calls on the name of the Lord. This is the cup of thanksgiving for deliverance, the response of a soul that's been rescued. Jesus took a different cup — the cup of God's wrath — so you could take the cup of salvation. Every time you give thanks, you're lifting that cup and remembering the price that was paid for it.
