Here are some short pithy gems from Charles Hodge:
To be in Christ--is the source of the Christian's life.
To be like Christ--is the sum of the Christian's excellence.
To be with Christ--is the fullness of the Christian's joy.
The grace of God exalts a man without inflating him--and humbles a man without debasing him.
The gospel is so simple, that small children can understand it--and it is so profound, that studies by the wisest theologians will never exhaust its riches!
Christian humility does not consist in denying what there is of good in us--but in an abiding sense of ill-desert, and in the consciousness that what we have of good is due to the grace of God.
This is true religion: to approve what God approves, to hate what God hates, and to delight in what God delights.
