The pastor who is ready to flee at the first signs of conflict in his pastorate, among his people, is not fit to be their pastor. The great Charles Haddon Spurgeon use to tell young men entering the ministry that if they can do something else, then they should.
Yes, the ministry is not for the half-hearted. The pastor must be prepared to give his all to the ministry God has called him to. And this ministry is going to involve anguish. Paul the Apostle and Pastor knew this all too well.
It is always good to be made much of for a good purpose, and not only when I am present with you, my little children, for whom I am again in the anguish of childbirth until Christ is formed in you! (Gal. 4:18-19 ESV, emphasis added)
When Paul wrote to these believers, he had to overcome the conflict that had arisen. You see, there were false brothers going around telling these believers that they needed Christ and the Moses Law in order to be saved–Christ plus. This is what Paul was up against. He knew this, and he was ready and willing to endure the “anguish” until Christ is formed in them, which is the model for every pastor.
A pastor who has been called to a particular local church must view his call as one of anguish until Christ is formed in his people. This must be his mission, his vision. He must not relent. He will be tempted to flee for “greener” pasture. But he must endure the anguish.
