This was the prayer of Apostle Paul for the Church of Philippi. “And I pray this: that your love will keep on growing in knowledge and every kind of discernment, so that you may approve the things that are superior and may be pure and blameless in the day of Christ,”Philippians 1:9-10 CSB 

I believe we need still need this prayer today. As different teachings are creeping in to deceive the people of God, we must be armed with the knowledge and truth of the Gospel.
