Taken seriously the ministry is not a cushy job. Many find that somewhere along the road they cannot hack it, and leave. Many find the expectations of men too great to cope with. Many expect too much from themselves. They forget that the Word is the power and that ministers are only sowers, instruments of the Almighty.
Serious ministers take time to pray.
In that sense the ministry is nothing special. All christians are to be full time servants of the Lord. But the church, as well as the community at large, needs teachers and pastors. It needs men with a love of the Word and a heart for their fellow human beings. It needs men who believe in the power of the Gospel.
