Revelation 8:4: “And the smoke of the incense, with the prayers of the saints, ascended before God from the angel’s hand.”
I and hope you often go with our prayers seemingly unanswered. We do not understand what happens in the spiritual world and so it is very difficult to say whether they were or not really answered. We cannot judge by what we see, because a lot more happens in the realm of the unseen than on the visible one. If you do not give up and continue believing your prayers (one day) ascend before God and the answer finally comes. Just do not give in and continue believing.
