In Philippians 3:1-2 Paul gives us two safety reminders for our protection. First, we’re called to rejoice in the Lord, which is a preventive measure to keep us from giving ear to what the false teachers are teaching. When satisfied in Jesus Christ the believer will see the utter foolishness to put any confidence in the flesh. Second, we are called to look out for the Judaizers who are out there teaching Christ plus works salvation.
