Now, justification in this life is given to us according to these three things: first by the laver of regeneration by which all sins are forgiven; then, by a struggle with the faults from whose guilt we have been absolved; the third, when our prayer is heard, in which we say: 'Forgive us our debts,' because however bravely we fight against our faults, we are men; but the grace of God so aids as we fight in this corruptible body that there is reason for His hearing us as we ask forgiveness.
Do you know who the upright of heart are? They are those who wish what God wishes. Therefore, do not try to twist God's will to you own but correct your will to that of God. The will of God is a rule of conduct. By it you have the means of being converted and of correcting your evil ways.
It is not the being seen of men that is wrong, but doing these things for the purpose of being seen of men. The problem with the hypocrite is his motivation. He does not want to be holy; he only wants to seem to be holy. He is more concerned with his reputation for righteousness than about actually becoming righteous. The approbation of men matters more to him than the approval of God.
Often a non-Christian knows something about the earth, the heavens, and the other parts of the world, about the motions and orbits of the stars and even their sizes and distances... and this knowledge he holds with certainty from reason and experience. It is thus offensive and disgraceful for an unbeliever to hear a Christian talk nonsense about such things, claiming that what he is saying is based in Scripture. We should do all that we can to avoid such an embarrassing situation, which people see as ignorance in the Christian and laugh to scorn.
Though defensive violence will always be 'a sad necessity' in the eyes of men of principle, it would be still more unfortunate if wrongdoers should dominate just men.
