The feast was over. The water and light show has dazzled the crowds. Jesus had offered living water to quench our thirst and added in John 8:12-30 that he is the light of the world. However, his hearers missed the message by challenging his procedure. In response, Jesus directed them back to himself as the "I am" and the one lifted up on the cross to die for the sins of all who believe in him. (full sermon notes)
As Paul demonstrated in his trial before Governor Felix, Christians must testify about Christ with our words and with our lives.
Not only did Christ die and rise for his people, but they also died and rose with him, liberating them from sin to live...
It’s one thing to say we believe, another to demonstrate it with what we do with our possessions and our abilities.
