14 And concerning you, my brethren, I myself also am convinced that you yourselves are full of goodness, filled with all knowledge and able also to admonish one another (Romans 15).
Paul has been writing on and on about how wrong it is to condemn one another over non-essential issues. Now we read where it is a very good thing to “admonish one another.” Whenever we begin a sentence with “Now, keep in mind …” we are alerting our hearer of something important about to follow. We are giving notice of a warning we want to put in their mind. This is the meaning of the word “admonish” here: “to put in mind,” as in a warning or caution or even a gentle reproof.
Being “able also to admonish” comes from being filled with two things: “goodness” and “knowledge” the former reflecting the right attitude, and the latter the right information. The right attitude comes from the Spirit (even as “goodness” is a part of the fruit of the Spirit given in Galatians 5:22), and the right information comes from God’s Word (which was authored by the Spirit, as well as is revealed or taught by that same Spirit). Thus, to be filled with goodness and knowledge is part of what it means to be filled with the Holy Spirit of God—who convicts sinners, and uses us to admonish saints.
Lord, we thank You for convicting us of our sins, and we thank You also for using us to admonish our brothers and sisters in Christ. Fill us This Day with all goodness and knowledge, that we might be useful vessels to admonish others when called upon. Amen.
