“Ye did not choose Me, but I chose you, and appointed you, that you should go and bring forth fruit, and that your fruit should remain: that whatever you ask the Father in My name, He may give it you.”  John 15:16

A merchant leaving his home and business, gives his chief clerk a general power, by which he can withdraw funds in the merchant’s name. The clerk is able to do this, not for himself, but only for the interest of the business.  It is because the merchant knows and trusts him as wholly devoted to his interests and business that he dares put his name and property at his command.  When the Lord Jesus went to heaven, He left His work, the management of His kingdom on earth, in the hands of His servants.  He could not do otherwise than also give them His name to draw all the supplies they needed for the due conduct of His business.

If such a privilege has been given us how foolish we are if we do not take advantage of it to the utmost.  The signed check is given us, how foolish if we do not present it.
