A delema [ Jude v3 ]

There is a Christian of long standing,he is in church,which is friendly,the minister is a nice person,who he prays for every day.It is an evangelical
church,but the minister lacks a evangelical voice,this  causes my friend great concern.For my friend knows that faith cometh by hearing and hearing
by the word of God.
   What can my friend do?,he does not want to cause trouble in the church,
before the present minister came,the church had experienced a lot of trouble
So again the question arises what should my friend do?to speak out or not to speak that is the question?.
    The words of our Saviour come to mind,speaking as regards His church,
that they may be one [John 17v21].It should always be our chief concern to promote unity within the church.In Psalm 133 we read,/Behold, how good and how pleasant it is for the brethren to dwell together in unity. Is this  always possible?, it may not always be ,but it appears to me,it should be our aim.
      It was the apostle Paul who had challenged Peter,who was by his
behaviour  compromising the truth of the Gospel[ Galatians 2 v11ff].Paul
puts this way,/I saw that they walked not uprightly according to the truth of the Gospel/.So it would appear to be acceptable to intervene when the truth of the Gospel is being undermined.
     The importance of unity is of major importance,and so the truth,
                                          A  prayer
Dear God grant that we will all we can to maintain unity,but help us also be faithful to truth in Jesus name Amen.
