John Trapp on Matthew 22:32

Verse 32. God is not the God of the dead] That is, in the Sadduces sense, utterly dead and extinct for ever, but in S. Pauls sense, Rom. 14. 9. He is the God of the dead. For the dead bodies also of the faithfull, whiles they lie rotting in the grave, and resolved into dust, are united to Christ; by means whereof a substance is preserved, sinne only is [illegible: 1 word] with it's concomitant infirmities. But the rotting of the body is but to refine it: it is but as the rotting of corn under the earth, 1 Cor. 15. 36. that it may [illegible: 1 word] more glorious. Once, death to the Saints is neither totall, but of the body only; nor yet perpetuall, but for a time only. See both these together, Rom. 8. 10, 11. Further, from this verse we may learn, That there is a two fold knowledge to be gotten from holy Scriptures. 1. Expresse, I am the God of Abraham, &c. 2 By due deduction and firm inference, God is the God of the living.
