The question of entering the ministry is an extremely important one. Only God can call a person to preach the Gospel. However, there are several considerations. You must KNOW that God has called you to the ministry and this must be tested over a period of time. Do you have a life of consistently living for God that is recognized by family and others? How does your pastor feel about your call to ministry? The bible says that a minister should not be a novice. This means you need to be properly trained and equiped for ministry. You must have a game plan. All of this will take time. Do not be in any hurry.
