When you think about a sponsor think about someone who gives you access to People, access to Places, and access to Provision. Think about them as people who sponsor you financially, and enable you to do things that you wouldn't otherwise have been able to do - perhaps the things that Jesus has called you to do. This is the Mentor As A Sponsor - the mentor as a benefactor.
In the book of Romans, Chapter 16:1&2, Paul writes,
”I commend to you, our sister Phoebe… I ask you to receive her in the Lord, in a way worthy of his people, and to give her any help she may need from you, for she has been the benefactor of many people, including me…”
Who are the sponsors in your life? Who are the people that have mentored you, and sponsored you? Who have given you access to people, have given you access to places, who have sponsored you financially and enabled you to do things you wouldn't have otherwise been able to do? Also ask yourself - Who can you be a sponsor to? Who can you help?
