If a person does not serve God, then sooner or later his love towards Him will grow cold and he will forsake God!
Serving God is one of the ways you and I can maintain a good spiritual shape. It is one of the ways to grow spiritually. If a person is always on the receiving side and never gives anything, he will eventually die. For this reason, it is very important to serve God.
There are so many people in the Church today who only call themselves believers; they simply go to church, read their Bible and pray; they fellowship with other believers, but serving God is not in the list of their priorities.
