We never can judge how low we have got until we see the place in which God first put us. Supposing I have to examine my ways as a Christian, I must bear in mind that a Christian is a man who is quickened with Christ and forgiven all trespasses, who is a member of His body and loved with the same love wherewith the Father loved the Son. Some are accustomed to think that, if a man is not a Jew or Turk or heathen, he must be a Christian. But when a believer hears that a Christian is one who is made a king and a priest to God, a purged worshipper―having no more conscience of sin, he becomes deeply exercised, feeling that he has not one right or full idea of his own calling and responsibility. He then begins to find a different standard of judgment in Christ, to measure how he ought to feel and work and walk for God, as well as for worship.
