My name is Dr. Jeff Reintgen, DDS. I am a general dentist in Cary, NC. Previously I was pastor of a local church in Latrobe, Pa. for ten years. During that time I taught the Scriptures basically three times a week. Now living in NC. I've been teaching a small Sunday school class for over three years. But frankly, I do not feel that this qualifies me to teach anything, especially the word of God. What qualifies anyone to write or teach would have to be a ministry gift given by Christ to the church (Eph. 4:11). But beyond this, the substance of what becomes doctrine and teaching must be received by the teacher himself -- the word of God taught to him by the Spirit of God. It must contain God's thoughts and be sound instruction, or else it simply adds to the works of man and what he is building on the earth. The Christian world is filled with the works of man; we have enough of this.
Christian teaching should always come from the Spirit of truth (John 15:26). It is not necessarily theological seminaries or bible training centers that give qualifications. For some time now I have prayed for myself and other believers the prayers found in Eph. 1:15-23 and Eph. 3:14-21. And I find that God answers, and is willing to make known what He has revealed. This is a most blessed experience, because it is based on the Christian's relationship with God, as son to the Father. Now we have received the Spirit who is from God, that we might know the things that have been freely given to us by God (I Cor. 2:12). All true believers have been sealed by the Spirit of God, and have this same Spirit given to us.
There are many things I have done that could be mentioned, but it is, like Paul, only confidences in the flesh (Phil. 3:3-7), and a good bit of earthly glory. I have to count these things loss for the excellence of the knowledge of Jesus Christ. This book is my effort to teach you what God has taught me, concerning His purposes, will, and plans. I believe you will find it will give you the means by which you may understand, again by the Spirit, the whole of Scripture. May God truly bless and enlighten you, as you read.
