Context

“Only those who are willing to hear the Word of God and then inadvertently fall into sin to their own great sorrow and regret, carry the burdens which the Apostle encourages us to bear. Let us not be hard on them. If Christ did not punish them, what right have we to do it? VERSE 3. For if a man think himself to be something, when he is nothing, he deceiveth himself. Again the Apostle takes the authors of sects to task for being hard-hearted tyrants. They despise the weak and demand that everything be just so. Nothing suits them except what they do. Unless you eulogize whatever they say or do, unless you adapt yourself to their slightest whim, they become angry with you.” source
