How can I do seminary well?

Join a church. Remember that the local church, not seminary, is God’s primary means for proclaiming the gospel, building up the saints, and preparing you for ministry (Eph. 4:11-16). Use your time at seminary as an opportunity to grow in your ministry and involvement in the local church, not to put the local church on the back burner.
Approach seminary with reverence. Thank God for the privilege of studying his Word. Fight to pursue the spiritual disciplines, to grow in love for God and his people, and to apply your studies to your heart. Practice guiding your studies of the biblical text, theology, and church history toward doxology, not a puffed-up head.
Approach seminary with receptivity. Be teachable. Pray for humility. Pursue relationships with your professors in order that you can learn from their teaching and their lives.
Approach seminary realistically. Seminary is not heaven. If you approach seminary hoping it will be a carefree academic paradise, you’ll be severely let down.
Approach seminary responsibly. Seminary is graduate school. Expect it to be academically rigorous. Prepare to work hard. And remember that there is more to training for ministry than academics. By God’s grace, strive to glorify him in every sphere of your life, especially the local church.
