Fosdick compared our understanding of God with our understanding of the sea. He said, "I know the sea but I don’t know the vastness of the sea. There is a part of the sea that washes up on the sands of my life. I can bathe in it. It lulls me to sleep with its waves. And yet, I know only a very little part of the sea."
It’s the same way with God, isn’t it? He is so close we can almost reach out & touch Him. And yet, He is so magnificent that we will never completely understand all about Him.
