"I am more afraid of my own heart than of the pope and all his cardinals. I have within me the greatest pope" - Martin Luther
In our work of reforming the church in our day, this statement from a great Reformer is a good reminder to us. There are errors within our churches which grieve us deeply because we believe they grieve God deeply. We do see insidious encroachment of paganism within the people of God as was described in the book of Judges where people practiced paganism in the name of Yahweh. These things should and do bother us. They even discourage us at times.
However, we must remember that we do not wrestle against flesh and blood, and our greatest battlefield is not out there anywhere but in our own hearts. Let us not become so engrossed with the planks in the eyes of the church out there that we become ignorant or careless about those in our own eyes. We must continue to be aware of our own need for being personally reformed according to the Word of God and growing in holiness. This will guard us from arrogance and infuse us with graciousness and mercy as we do the necessary task of pointing out error. One cannot truly labor for the purity of the church while bypassing the pursuit of personal purity.
