Some would define a servant like this: 'A servant is one who finds out what his master wants him to do, and then he does it.' The human concept of a servant is that a servant goes to the master and says, 'Master, what do you want me to do?' The master tells him, and the servant goes off BY HIMSELF and does it. That is not the biblical concept of a servant of God. Being a servant of God is different from being a servant of a human master. A servant of a human master works FOR his master. God, however, works THROUGH His servants.
Henry BlackabyWhen we hear His call and respond accordingly, there will be no limit to what God can and will do through His people. But if we do not even recognize when He is speaking, we are in trouble at the very heart of our relationship to Him.
