A Southern Baptist guide to converting Unitarians:
Secular humanists are basically atheists who deny the very existence of a personal living God. Therefore, arguments for the existence of God prepare the UUA heart for evangelism. It is very difficult to apply John 3:16 to the life of someone who rejects the very existence of a God who loves the world so much that He gave His only begotten Son. There are several compelling arguments for the existence of God, but space does not permit us to look carefully at them here. The two most common evidences for the existence of God are the very existence of the universe itself, and the intricate design of the universe. These arguments are called the cosmological and the teleological arguments respectively. Basically, the cosmological argument argues for God on the basis of the presence of the universe. If there is a universe, then there must have been a Universe Maker, God. The teleological argument argues for God on the basis of the design of the universe. If the universe looks like it has been designed, then there must have been a Universe Designer, God. Please consult the appropriate FAITH training materials that dedicate sessions to apologetic arguments for the existence of God.
