And yet we do not act. According to the Midrash, God did not split the Red Sea until the children of Israel walked in up to their necks. Even when it comes to miracles, God wants us to get as far as we can by ourselves. Do not rely on miracles to bolster your faith. If we keep doing the things we've always done, we're just going to get the results we've always gotten.
Many people effectively excuse themselves from life.
They are too old for this. But first we have to get wet.
