Rise and enter into the city, and it shall be told thee what thou must do. Acts 9.6.
What the Lord meant by this was: I will not tell you what you are to do, but somebody else will do so. The Lord used someone else to tell Paul. This is a revelation of the body of Christ. On the first day of Paul’s salvation, the Lord revealed to him the law or principle of the body.
Though Paul is to be a vessel mightily used by the Lord, the Lord nevertheless uses other people to help him. Hence let us never think we do not need to depend on others as though we are to get everything directly from God alone.
True, this is not meant to teach us to follow other people blindly, but it does admonish us not to entertain such a lofty attitude wherein we believe we by ourselves may receive the word of the Lord and solve all problems singlehandedly.
