QUESTION: How does one become discerning? How do believers in the Lord Jesus Christ guard themselves from becoming just another part of evangelicalism's groupthink on issues? How does one not become a slave to culture's conventional wisdom?
ANSWER: Think biblically. Be students of God's Word. Have your mind guarded and guided by the truth of Scripture. Be heavenly-minded on earthly things. Be Bereans. Love His law. Meditate on it day and night. Hide it in your heart. Let it become your sojourners song. Let it take permanent residence in you. Turn to it as lamp to your feet and a light to your path. Treasure it more than silver or gold and feast upon it more than your daily food. Let it be the joy and rejoicing of your heart. Crave it as newborn babes and find its words sweeter than honey and the honeycomb.
"Rejoice in the Lord always; again I will say, Rejoice. Let your reasonableness be known to everyone. The Lord is at hand; do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.
Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things."
