Sola Scriptura

I will instruct you and teach you in the way you should go; I will counsel you with my eye upon you.

Therefore, knowing the fear of the Lord, we persuade others. But what we are is known to God, and I hope it is known also to your conscience. We are not commending ourselves to you again but giving you cause to boast about us, so that you may be able to answer those who boast about outward appearance and not about what is in the heart.
