Fear and Trembling

Psalm 2:11
"Serve the LORD with fear, and rejoice with trembling."

I'm afraid now and then that all Christians are guilty of forgetting Who they serve. We are the children of Love personified. Yet He also is the very being of Justice and Righteousness. He is the Judge Who will condemn the unrepentant. The Holy One Who turned His back on His only Son when He became sin for us.
God is Love, and His mercy is boundless and unknowable for its vastness. Yet we cannot focus on that to the exclusion of His other qualities. Serve Him because of love, but do it with fear. Rejoice in His mercy and grace that is poured out daily in our lives, but do it with trembling. Not fear and trembling as the world knows it, but that staggered awe, honor and respect that the King of Righteousness deserves.
How do I feel about the seeming dichotomy of God's character? How should that influence the way I live today?
