“ A Jesus Follower can explain our One God in Three Persons is like an equilateral triangle. Both have three, conjoined, and distinct but identical parts. This is a simple way to help non-Followers of Jesus who struggle with the concept of Trinity to better understand the Three Personalities of our One Living God...God the Father, God the Son and God the Holy Spirit. ~ gfp '42© ”
