Live truth instead of professing it.
It is necessary to the happiness of man that he be mentally faithful to himself. Infidelity does not consist in believing or in disbelieving it consists in professing to believe what he does not believe.
I'm still going to make mistakes but I don't have any problems with publicly professing my faith now. It just took me a long time to get to the right place in my relationship with Christ.
Though I am a Catholic a professing one I have serious doubts about the survival of the human personality after death.
