Dr. Michael Horton and Adriel Sanchez answer caller questions. Key questions answered in today's show: 1. Why is it so hard to become Holy? It seems like a really basic command that God gives, but the more I strive the less progress I seem to make. 2. How exactly can you prove that God, Jesus, the whole thing is real, that it’s the only religion? If it was real there wouldn’t be any other religions but him. If Christianity is true why are there are other religions? How do you explain that a mortal man could go through a stone that wasn’t moved? 3. What do you think is important for new believers to understand about worship? 4. What does it mean to be a “doer of the word” and not a “hearer”?
