David knew that God had called him before he went to work for King Saul! that's important! You've got to know who you are, apart from what you do, otherwise you'll end up working harder at being appreciated than you will at your job. That not only sends the wrong signal to your co-workers and supervisors, it robs you of your true identity in Christ, plus the solid foundation of security, peacefulness and joy your job provides. Instead your selff-worth will fluatuate like a politician's popularity in an election year, up one day and down the next.
You will end up riding a roller coaster of moodiness and unexpected disappointments, alongside a few moments of praise, which may or may not be sincere; for once others learn that you thrive on recognition, they hold the key to manupulating you for their own purposes.
Thirsting for recognition gives others power over you. Power to define you and influence you. That's dangerous! It's hard to hear God's vioce (often directing you against the tide of popular opinion) when you've tuned your ears to respond only to the boss's voice or the customer's remarks. Listen: "Whatever you do, do all to the glory of God." ( 1 Corinthians 10:31 NAS).
Whether you're pusing a broom or planning a budget, do it as unto the Lord! When you experience God's pleasure in what you are doing, even if it is something you don't particularly like doing but know that it is where you should be at the present moment, you don't need anybody else's affirmation. You only need to know that you have approved by God.
Have a great rest of the day, and:
Don't Forget To Say Your Prayers!
