While it is impossible to prove (or disprove) God’s existence (Heb. 11:6), the evidence screams out, “There IS a God!” For one, consider the design of this universe (Psalm 19:1-6); while the odds of life on any planet are astronomically impossible, we exist! Our bodies are so finely-tuned that we really can refer to the “miracle” of life. In addition, if morals are subjective, then how can we understand that it is wrong to torture babies for fun? The atheist has no foundation to support why something is right or wrong. Finally, the bodily resurrection of Jesus shows there is a God (1 Cor. 15:1-5). If Jesus was not raised by the power of God, then the skeptic must produce evidence to support another theory.
