Luke 1:1-4

vs. 3-4
Luke is saying he wrote this book to Theophilus so that Theophilus would know with 100% certainty that all he has been told and instructed about Jesus was true.

God puts people in our lives that become our mentors.  People who have struggled and overcome, who have grown close to Him in their walk, who have an intimate relationship with Him!  God gives us these people to encourage and build us up, to help us find strength when we are down, to show us faith when we doubt, and (even though we may hate them for it) to point out the wrong we do in our walk with God.

We as humans need encouragement, need building up, need socialization!  We thrive off others even though we may not realize it.  God created us for community and fellowship.  We need to surround ourselves with the people who build us up in our relationship with God.  People we look up to because of their faith and their relationship with God.
