Can fear be productive when approaching God?

[mee]

"Fear the true God and keep his commandments. For this is the whole obligation of man."—ECCLESIASTES 12:13.
"If only they would develop this heart of theirs to fear me and to keep all my commandments always."—DEUTERONOMY 5:29.
Fear of God is a feeling Christians should have toward their Maker. One definition of this fear is "an awe and a profound reverence for the Creator and a wholesome dread of displeasing him." Thus, fear of God influences two important aspects of our lives: our attitude toward God and our attitude toward conduct that he hates. Obviously, both aspects are crucial and deserve careful consideration. As Vine’s Expository Dictionary of New Testament Words points out, for Christians this reverential fear is ‘a controlling motive of life, in matters both spiritual and moral.’
