Thank you for this bit of information you have given regarding your friend and about him supporting your ministry financially. It helps a lot to interpret this dream.
In my opinion this dream speaks of your friend encouraging you to run with your ministry. He’s pushing you forward in the Spirit. He wants you to be successful .It is evident from your background information that he respects you and obviously your ministry too, therefore he supported you financially for this purpose. I feel this action of him hitting you on the shoulder and patting you on the shoulder is also him saying “God is with you and will give you strength to do the work of the ministry.”
In this dream God is exhorting you to run with your ministry and to know he will give you the strength to do so.
