From Ezra 4:1 - In every door God opens for His people is Satan working his best to trip us up and close the door by desecration, discouragement, despair, or division. The sad truth is that sometimes he is successful.

From "God's Work supplied" - Ezra 1:1-9 " When God moves and opens a door to do His will, He stirs in men's hearts to serve and supplies the needs by others giving money & materials so all have a part and God's work is completed" or as Hudson Taylor said, "God's work, done God's way, never lacks God's supply"

From "Doing God's work" - Ezra 3 "There comes a time in our service for the Lord where we move from available willingness to actual work."

Behind every "open door' of opportunity stands our God ready to help us and say at it's end "well done".
(Revelation 3:8)

We carry the "burden" of God's message not as a weight to get us down but as a gift to share" (Malachi 1:1)
