The Talmud teaches: "Whoever designates a permanent place [makom kavua] for his prayer, the God of Abraham assists him."
The Shulchan Aruch (Code of Jewish law) recommends having a regular synagogue and a makom kavua there.
Abraham is the model for someone who prayed repeatedly in the same place. "Next morning, Abraham hurried to the place where he had stood before the Lord" (Genesis 19:27). This was the morning after the destruction of Sodom, as well as of God's refusal of Abraham's petition to spare them.
Yet Abraham returned to that same place again. He did not stop praying because God had said "no".
A makom kavua is symbolic of our dedication to prayer through all life's ups and downs, the goal that our "devotion of the heart" remain steady. It also means that people know where to find you. The ideal, then of makom kavua is both a commitment to God and those around us.
