EXPERIMENT.In 2Co_9:13 experiment means proof: by the experiment of this ministration they glorify God. It is proof arising out of experience, as in Hall, Works, iii. 467: We have known, indeed, some holy souls, which out of the generall precepts of piety, and their own happy experiments of Gods mercy, have, through the grace of God, grown to a great measure of perfection this way; which yet might have been much expedited and compleated, by those helps which the greater illumination and experience of others might have afforded them. Cf. preced. article.
