Today, Rev. Joshua Patty preached about the general themes of miracles and salvation in the book of Exodus: "Behold God's Mighty Hand." Drawing primarily from the miraculous parting of the Red Sea for the Israelites to walk through, he talked about how the entire story of Exodus is a story of salvation of the Israelites. Sometimes the miracles are dramatic, such as God speaking to Moses out of a burning bush. Other times, the miracles take longer and are more subtle, as God patiently works to reform the Israelites' identity as slaves into a free people of faith in God.
This painstaking process was not without set-backs, as when the Israelites made a golden calf to worship. It also was not quick, lasting for two generations. Sometimes, we too expect miracles to happen dramatically and "in a flash." Occasionally, they do, but more often God's salvation takes longer to achieve in our lives too.
