“I have confidence in you, in the Lord, that you will have no other mind; but he who troubles you shall bear his judgment, whoever he is.” Galatians 5:10
Paul is writing to the Galatians because there are people who are saying and teaching things that are not in line with the true gospel, that is, Christ and His life and teachings as He Himself has revealed. At least some of the Galatians are being confused and led astray by these other teachings, and Paul seeks to correct their understanding and bring them back into the fold. Here, he is expressing his belief that they will recognize and return to the truth, and that those who are causing these problems will be dealt with accordingly.
How very like our situation today! So many different denominations, and within those denominations different teachings, different schools of thought and interpretations of the Bible. How are we to know the truth? Unfortunately, we do not have Christ Himself among us; nor can we speak to those who were with Him during His earthly ministry. We do, however, have the Bible, the Word of God; that must be our standard of truth. Through prayer and the Holy Spirit, each and every one of us can come to understand even the most difficult and obscure passages:”If any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach, and it will be given to him” (James 1:5); “And you will seek Me and find Me, when you search for Me with all your heart” (Jeremiah 29:13).
