Place a substantial meal before a tired man and he will eat with effort and be little better for it at first. Give him a glass of wine or brandy, and immediately he feels better: you see him come to life again before you.
I'm thinking, "What difference will this sermon make in their lives tomorrow? What am I trying to give them that will make a difference?" For example, had to do with the theme that Jesus will not let go of you. He's holding onto you. I talked to them about the disciples and Peter on the night before the crucifixion of Christ - how Jesus said that all of you are going to turn away, but He would be waiting for them in Galilee.
