I know God is real.
By the hundreds of prophecies in the Bible that have been fulfilled.
By the power of the Bible to discern the thoughts of our hearts and to transform our lives.
By the wisdom of the Bible, which is the biggest influence upon Western Civilization and the cornerstone for the greatest nation in history.
By the truth of the Bible, which has persuaded the hardest of skeptics who have dared to examine it.
By the way God's Spirit has spoken to my heart exactly what I needed to hear, when I needed to hear it, for almost thirty years.
By the miracles of healing I’ve received.
By the testimony of the eyewitnesses of the resurrection of Christ, who were willing to die for their faith (if it was a lie, why would they die?).
And by this:
Jesus claimed to be the Lord, the source of life, the only way to Heaven. Either he is or he isn’t. If he isn’t, either he knew it (he's a liar) or he didn’t (he's a lunatic).
So he has to be either Lord, liar, or lunatic.
His words inspired ten of his closest friends to lay down their lives for him. His words have been universally acclaimed as the wisest ever recorded. His words have inspired many millions--from self-righteous moralists to serial murderers--to change their ways and follow him.
Lunatic? Come on.
He accepted the arrest, the whipping, the fists, the interrogations, the crown of thorns, the crowd's scorn, and the cross without changing his story.
Liar? Get real.
Jesus is Lord.
