Have other people been encouraging you to do so? I believe that if God is leading you to go into ministry and to go to seminary (which, in my book, should not be separated), then He will normally encourage you through other people. Whether it be teaching, preaching, or counseling, people must have seen a gift in you and said “Hey, have you ever thought about going to seminary or getting into the ministry?” Let other people help establish the reality of your qualifications. It is necessary to have many counselors.

Seek out opportunities. This implies much contact with people in the church. If you are not involved in the church right now, don’t even bother … there are other issues with which you need to deal. And (standing on soapbox) don’t say to yourself, “I don’t go to church because all churches are too corrupt,” or “I can’t find a church that I can have fellowship in, that is why I am going into ministry.” We don’t need any more of this type of vigilante “I’m-going-to-fix-everything” attitudes in the church. There are plenty of those already, thanks. Who knows, someone in the church might sponsor for your ministry schooling. If you have that burning desire in your heart to serve God and minister to people to share the good news of our Lord Jesus Christ then it is your calling. Pray to God our Father in Heaven yourself and don't rely on other people praying. I'm not saying we are not to ask other people to pray for us because we do need others to pray for us sometimes but to have a 1-on-1 relationship with God, you have to talk to God first. God Bless.
