With that foundation, we can look at who God the Father is. God the Father is the first Person of the Trinity and serves as its functional head. He is an infinite, personal Spirit (John 4:24) and has been identified as “Father” from eternity past, both to His Son (John 3:16–17) and to His chosen people (Exodus 4:22–23; 1 Corinthians 1:3).
