Be what you profess!
You profess to be a Christian: be a Christian.

You say that you are a follower of Christ: follow him, then.

You know it is right to be a man of integrity and uprightness:
be so.

Count all things but dross that you may be a true man,
a godly man, a holy man, a Christly man.
-Spurgeon, "The Sons of God"
