2 Corinthians 1:12
12 For our boasting is this, the testimony of our 1aconscience, that in 2singleness and 3bsincerity of God, not in 4fleshly cwisdom but in the 5dgrace of God, we have conducted ourselves in the world, and more abundantly toward you.
123 A divine virtue, a virtue of what God is. To conduct ourselves in such a virtue means to experience God Himself. Hence, to conduct ourselves in such a virtue is to be in the grace of God (later in the verse).
