Promise is more important than the land

Acts 7:1-10
They charged Stephen talk nonstop against this Holy Place and God's laws.
Stephen's lengthy defense takes the form of a review of the nation's history.
God gave inheritance to Abraham and gave him nothing, not so much as foothold.
Why?
God sees the people inheritance is more important than the land.
God's promise shell be done, but could not be seen at that moment.
Jews always connect the land with God, but God gave Abraham promise but not land at begining. More important is the promise not the land.
How?
Look at the promise instead of the land. Help me have the faith to God's promise.
