The second of two back-to-back talks given at the "Who made God" conference at the Campus Church, Welwyn garden City, UK on 27 Feb. 2016, the first talk being "The necessity of God" ... an argument derived from current atheistic cosmologies! This second talk complements the first by identifying the specific characteristics of the biblical God. The presentation is based on Paul's address to the Athenian philosophers in Acts 17 and locates three cosmic 'identifiers' and three relational 'identifiers' that distinguish the true God from all imitations. These identifiers lead logically to the gospel of salvation through faith in Jesus Christ.
