When Abram was ninety-nine years old the Lord appeared to him and said, 'I am El Shaddai. Live in my presence, be perfect. Genesis 17:1
God's command to live in His presence signifies the freedom and openness we should have in our relationship with Him. We are not to hide among 'the trees of the garden' - the various allurements of sin - like our first parents. God's call for each one of us to be perfect signifies the exalted vocation He demands from us - He accepts no compromise on perfection.
