Your eternal well-being hinges on what you think of Jesus, and what you do with Him. Just believing that He was a good teacher is not an enough. You must accept Him for who He really is – the Eternal God who condescended to to us, and became a human being. He was born in a stable, lived a sinless life, performed miracles, preached the Gospel, forgave sins, died on a cross, rose again the third day, ascended to Heaven, is seated on the right hand of the Father, and is coming again one day to receive His own unto Himself and to establish His righteous Kingdom on Earth.
