What did Les say would happen if he tried to follow someone walking on the Sea of Galilee?
If he tried to follow someone walking across the Sea of Galilee, he could not do it; he would go down, like Peter. He explained that Jesus walked on the sea as God, and no mere human can walk in God's steps. Being only human, he would sink rather than follow.
Les explains that when Jesus walked the footsteps of Galilee and across the Galilee Sea, He was God. Because of that, Les says, “I can't walk in the steps of God.” He put it graphically to one individual who started walking across the Sea of Galilee: “I couldn't follow. I had to be like Peter, I'd go down.” This fits his larger point from Philippians 3:17, where Paul tells Gentile believers in Philippi, “Brethren, be followers together of me, and mark them who walk so as you have us, Paul, as an example.” Les clarifies that this does not take anything away from the Lord Jesus, but Jesus was God, while Paul was just as human as Les is.
