Acts 17:11: “Now the Berean Jews were of more noble character than those in Thessalonica, for they received the message with great eagerness and examined the Scriptures every day to see if what Paul said was true.”
Being “critical” as you listen to a sermon is not a sin — in fact it is what God expects of you. Even the apostle Paul underwent “editing” by the Berean Christians — and the latter were described as being “of more noble character” because of it.
Listen with a discerning heart and mind, and read your Bible to see if what is being preached to you is consistent with it. The blessing does not come from simply hearing the word but in understanding it and putting it into action. Don’t just sit there: think.
Remember Philippians 1:9-11: “And this is my prayer: that your love may abound more and more in knowledge and depth of insight, so that you may be able to discern what is best and may be pure and blameless for the day of Christ, filled with the fruit of righteousness that comes through Jesus Christ—to the glory and praise of God.”
