Dwelling in tents

"By faith Abraham obeyed when he was called to go out to a place that he was to receive as an inheritance; he went out, not knowing where he was to go. By faith he sojourned in the promised land as in a foreign country, dwelling in tents with Isaac and Jacob, heirs of the same promise; for he was looking forward to the city with foundations, whose architect and maker is God." (Hebrews 11: 8 - 10)

Why is this scripture one of the PL scriptures?  I was attracted by the fact that Abraham showed the obedience of faith when he left his native land for a foreign country not knowing what to expect.  The Enterprise is a journey of faith.  It is a journey where I pray every day that the joys and sorrows, the delays and disappointments will make for the growth of faith, patience, wisdom, humility, courage, peace and contentment.
