Our Teffillos are answered quicker than other times depending on two factors:
1. Our closeness and oneness with Hashem
2. Our goal to merge the physical and spiritual worlds
Three examples of individuals who were answered right away:
1. Moshe Rabbeinu davened that Hashem show him that He rests his holiness on humans
2.Shlomo haMelech asked that the Shachina should rest on the Bais haMikdash again- merging the two worlds
3.Eliezer, Avrohom’s servant, davened for the marriage of Yitzchok and Rivka. Yitzchok came from a holy home, unlike Rivka - again beseeching to merge the two worlds.
Conclusion: the closer these two worlds unite the quicker the realization of the Bracha.
