promissive

promissive (comparative more promissive, superlative most promissive)

1. Making or implying a promise; promising.
   • 1844, Edward Polhill, The Divine Will Considered in Its Eternal Decrees, page 191:

     I answer, that the word may be considered under a double notion, either as it is operative of faith, or as it is promissive of rest to believers: take it as operative of faith, and so it profits, not being mixed with faith, otherwise faith could not come by hearing, as the apostle asserts, (Rom. x. 17); but take it as promissive of rest to believers, and so it doth not profit, not being mixed with faith; that is, faith, which is the condition of the promise, not being performed, the eternal rest, which is the thing promised, cannot belong to them: and this is clearly the apostle's meaning;

   • 1847, John Johnson, Theological Works, page 136:

     The performing of the promises cancelled the promissive words; for if they were yet promissive, then what was promised is not performed; this was promised by certain signs. Those promissive signs are cancelled, because the promissive Verity is exhibited.
