Please tell me where it is in the bible God gives us 70 years in this life.?

Psalm 90

If what you mother-in-law said was true, how do you explain the faithful who have died far younger than the age of 72?

Moses 'Wrote My Spirit "(God"s) will not always strive with Man;Therefore Man"s Life 120 yrs.This was at time Human Government was Established after the Flood; (Moses wrote the 90 th Psalm )with 70 yrs being Man"s Life Span,and maybe even 80; But there would be Testing or Trials;

Should a Person LIVE 70 Yrs with life in all areas

of a Person"s Life; Be Thankful to God,Cause a lot of People don"t make it;

The years talked about in the Bible are actually based on the planting and harvesting seasons, so it is quite possible for the aged to live up to 70 or more harvests. All that aside, God gives no guarantees.

my loyal christian father died @ 66 years old

it was a total shocker

I think you are looking in Psalms and Proverbs

apparently it's a lie

many christians die in tsunami's, earthquakes, disease

We are not guaranteed any length of life.

Any of us can die anytime.

If one dies a 'natural' death, it is often around 70, or 80 years of age.

That's what Moses referred to in Psalm 90:10

Your mother in law was wrong.

Dann my in-laws, they are in their very late 80. still alive.
