"If His grace is an ocean, we're all sinking"
According to Answers.com, 71% of the world is made up of ocean. That is a lot of water. The concept of God's grace and the imagery of an ocean is so beautiful.
When I was a little girl, my dad told me to always be careful when swimming too far out in the ocean, because tidal waves (or that is what I called them) could sweep you too far out and you wouldn't be able to swim back. The ocean is very very powerful. It can rage with anger, or be calm with peace.
If the world is made of 71% ocean, that means the ocean overtakes most of the earth. Compare that to God's grace. God's grace covers every thing we do, just like the ocean covers the earth.
There is nothing we can do to separate us from God's love and God's grace.
Romans 8:38-39, "For I am convinced that neither death nor life, neither angels not demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation will be able to separate us from the love of God that is in Christ Jesus our Lord."
