On one occasion, in a Bible study of the church, I asked the congregation there: what does the word grace mean? Everyone replied that it is an undeserved gift from God. The answer seems correct, but technically it is not, since I never asked the meaning of God’s grace, which would be totally different. If we define the word grace by itself, it would be a favor given to us that we do not deserve, in general, in any context, whether Christian or not.
It is important that we understand this, that there are words that must be defined by themselves and that the final touch will be given by the context in which we are speaking. I ask today, what is sound doctrine? This will depend to a large extent on the context in which you find yourself, but the reality is that if we speak in the context of the Christian faith, a single meaning, regardless of our human opinion.
