1 John 5:14-15

14This is the [remarkable degree of] confidence which we [as believers are entitled to] have before Him: that if we ask anything according to His will, [that is, consistent with His plan and purpose] He hears us.

15And if we know [for a fact, as indeed we do] that He hears and listens to us in whatever we ask, we [also] know [with settled and absolute knowledge] that we have [granted to us] the requests which we have asked from Him.
