When we go to the Old Testament, where the term ‘the fear of the Lord’ is very common, we come upon some very puzzling usages. Often the fear of the Lord is linked with great joy. Proverbs 28:14 tells us that ‘Happy is the one who feareth always.’ How can someone who is constantly in fear be filled with happiness? Perhaps most surprising is Psalm 130:4, where the Psalmist says, ‘Forgiveness comes from you — therefore you are feared.’ Forgiveness and grace increase the fear of the Lord. Other passages tell us that we can be instructed and grow in the fear of the Lord (2 Chronicles 26:5; Psalm 34:11), that it is characterized by praise, wonder, and delight (Psalm 40:3; Isaiah 11:3). How can that be? One commentator on Psalm 130 puts it like this: “Servile fear [being scared] would have been diminished, not increased, by forgiveness…The true sense of the ‘fear of the Lord’ in the Old Testament [then]…implies relationship.”
Obviously, to be in the fear of the Lord is not to be scared of the Lord, even though the Hebrew word has overtones of respect and awe. ‘Fear’ in the Bible means to be overwhelmed, to be controlled by something. To fear the Lord is to be overwhelmed with wonder before the greatness of God and his love. It means that, because of his bright holiness and magnificent love, you find him ‘fearfully beautiful.’ That is why the more we experience God’s grace and forgiveness, the more we experience a trembling awe and wonder before the greatness of all that he is and has done for us. Fearing him means bowing before him out of amazement at his glory and beauty. Paul speaks of the love of Christ ‘constraining’ us (2 Corinthians 5:14). What is it that most motivates and moves you? Is it the desire for success? The pursuit of some achievement? The need to prove yourself to your parents? The need for respect from your peers? Are you largely driven by anger against someone or some people who have wronged you? Paul says that if any of these things is a greater controlling influence on you than the reality of God’s love for you, you will not be in a position to serve others unselfishly. Only out of the fear of the Lord Jesus will we be liberated to serve one another.
