Israel had all the signs that should have shown them that God was with them. Instead, we find Israel in Exodus 17 asking "Is God among us or not." It's OK to be thirsty, it's OK to ask for water, it is not Ok to test God in our forgetfulness and refusal to listen. As Christians, we also have evidence enough that shows us that God is present. May we be encouraged to remember what God has already done for us and be willing to LISTEN to Him.
