You can tell how well someone knows another person by how he or she addresses that person. If the name someone uses to address another person remains formal like "sir" or "ma'am", chances are he or she isn't too familiar with the person to whom they're speaking. In Mark 8, Jesus invites Peter to declare his name for Him by asking, "Who do you say that I am?" And in this sermon, Pastor Rich presents the same question to us. The way we respond becomes an indicator for the kind of relationship we share with God.
