Jeremiah 1:5 (NIV) "Before I formed you in the womb I knew you, before you were born I set you apart; I appointed you as a prophet to the nations."
Acts 9:6 (NIV) "Now get up and go into the city, and you will be told what you must do."
Acts 26:16 (NIV) "Now get up and stand on your feet. I have appeared to you to appoint you as a servant and as a witness of what you have seen of me and what I will show you."
Working for Christ has today been accepted as the ultimate test of godliness among all but a few evangelical Christians. Christ has become a project to be promoted or a cause to be served instead of a Lord to be obeyed. Thousands of mistaken persons seek to do for Christ whatever their fancy suggests should be done, and in whatever way they think best. The what and the how of Christian service can only originate in the sovereign will of our Lord, but the busy beavers among us ignore this fact and think up their own schemes. The result is an army of men who run without being sent and speak without being commanded. --
