We have to be careful to not fall into the trap of trusting a man or a ministry over God's Word. If a minister is teaching or preaching any other truth than that which is found in the Bible, then he is leading you astray and he will answer to God. Paul did not consider those that were "influential" when making plans or teaching. He was only concerned with Jesus and Him crucified and that is what he preached until his end. We too must only teach what is in the Word. We must never fall in the trap of believing that we know better than God himself.
