The right road always leads to the right place; therefore, get on the right road and go as far as you can on it.
There is only one thing to do about anything; that is the right thing. Do right.

God in the right place in my life fixes every other relationship of life. (Matthew 6:33)

It is wrong to be yoked to one who refuses the yoke of Christ.
The part of your character that is deficient is the part that needs attention.
Don't quit. Finish the job. God can't use a quitter.
Anything you do that hinders your progress for God is wrong.
Beware of any society in which you feel compelled to put a bushel over your testimony.
It isn't enough to be good. Be good for something. The essence of Christianity is not a passionless purity.
Positive living produces negative effect.
Learn to be sweetly firm.
