Another reason to let the Lord be Lord of our lives because He has the perspective to eternity past to eternity future: "To the only God our Savior be glory, majesty, power and authority, through Jesus Christ our Lord, before all ages, now and forevermore! Amen," Jude 1:25.
Ernest Hemingway: "If a writer... knows enough of what he is writing... he may omit things that he knows and the reader, if the writer is writing truly enough, will have a feeling of those things as strongly as though the writer had stated them. The dignity of movement of an ice-berg is due to only one-eighth of it being above water. A writer who omits things because he does not know them only makes hollow places in his writing."
