Do Christians look like perfect people? No. We have to sincerely try our best to live as Christ would have us live, but we are not able to be perfect at doing that. Read Romans 8  - we have to be different from the person we were when we put on Christ in baptism. Now we are held to a standard -- be like Christ! Yet, this is not a call to be perfect, because mercy and grace still wash us as long as we reject the old life of sin. 2 Corinthians 5:11 and the following several verses tell us that God knows us. The love of Christ compels us so that we don't live for ourselves, but for God. Levi also goes into the chapter of Hebrews 4 on this topic
