God provided angelic announcers when the world took no notice.
James 4:10 "Humble yourselves in the sight of the Lord, and he shall lift you up."
In your service for the Lord, do not concern yourself with being seen and noticed by man. Most of the time, people do not notice or understand the sacrifice we make to serve the Lord. They cannot see our heart or know our motives.
We will, in most cases, not receive adulation for our service to the Lord.
But God knows.
He sees our sacrifice. He treasures our work.
When you feel that no one notices, remember the Heavenly Host that is looking down on us; and rejoice with them that the work of God is being accomplished here on earth.
