For the past  years Dr. Sos teaches seminars on Leadership related issues at Gran Rey Church. Dr. Hugo Weiss is a visionary who understands that the ministry in the Kingdom of God can only advance if the workers are properly equipped with skills and knowledge of the ministry. Dr. Sos taught a variety of subjects on administration of the church, theological themes, ethical issues of  church and spiritual warfare.  The growing church needs more space to accommodate the people.  The weekend  ministry  begins with the youth service on Saturday and three services on Sunday for adults. The church has also planted several churches in the North and is extending the ministry into Brazil and Spain. They are supporting missionaries and helping with the construction of church buildings. Dr. Weiss is  a hard working minister and his life inspires many other pastors in the country. The ministry on the weekend was very powerful.
