Abraham was 75 years old when God showed up and said, leave your country, your people and your father’s household and go to the land I will show you.” (Genesis 12:1)
Think about that for a second. 75. Most of us are hoping to be long retired by then. And here God was taking a man and changing the course of human history. Apparently the excuse “I’m too old” or “I’m too tired” or even “Haven’t I worked hard enough already?” doesn’t hold much weight with God.
