According to Moses in Psalm 90:10, the average lifespan of a human being is 70-80 years. In verses 1-4, he depicts God as eternal and the brevity of the life of humans. In verses 5-10, Moses laments about the life of the Israelites who were wandering in the wilderness for 40 years without entering the promised land. Have I accomplished God’s will thus far? How much longer do I have on earth? What does the Lord still want me to do?
