Deuteronomy 30:20

By loving the Lord your God, by obeying His voice, and by holding closely to Him; for He is your life and the length of your days, that you may live in the land which the Lord promised (swore) to give to your fathers, to Abraham, Isaac and Jacob.

The amount that we love the Lord and trust in His promises will reflect in the amount we receive our promised land.  When we are willing to do our part, God can do His part.  If we feel we are not receiving from God, then do a heart check.  Spend time with the Lord, and He will direct us back on the path so the blessings may flow.
