The single most important thing in my life, over the past 2 years, has been who I intentionally allow to influence me. If I surround myself with people who have the same skill set, the same amount or less experience than I do, the same passions, the same knowledge, the same convictions, etc....then I limit my ability for God to teach me.
Currently I have an accountability partner who struggles with things that I am strong in and I struggle in things the he is strong in, this allows stern correction, strategic guidance, and honest prayer. Also, I have 3 people who I consider mentors all in which are people who I could call on any given day for any particular reason. All three of these people have different strengths, minor theological differences, gift sets, etc. I think that the more I broaden myself, the more God works in me.
