Explain the meaning of salt light

Yes means yes, which includes both "it can only be so" and "it must be so", excluding the meaning of "already so". Some people say that when a person believes in Christianity, he will naturally become the salt and light of the world, so it seems that Christians will become saints once and for all as long as they are baptized. This understanding is not accurate, because the meaning of "yes" here is eternal, and it is for any generation and any era, which means neither the past nor the future. It is always in the present continuous tense.

Secular: The world is the world. The world we live in is created by God and is very rich. God allows us to live in it and let us feel the existence of God. Specifically, it is the surrounding environment where we live. Everyone has a place in the world created by God. This is God's grace, and we are all accepting God's grace. The surrounding environment in which we live reminds us of our material living environment and also reminds us of our spiritual living environment. Our interpersonal life environment, family life environment, working life environment, as well as our cultural environment, our psychological environment, interpersonal communication and business environment.
