“The vision that drives Biblical Training is twofold. The first part of the dream is that every Christian should be educated and equipped for the fullest use of their spiritual gifts in serving others for Christ’s sake. The second part of the dream is that Christian education up to seminary standard should be available free to anyone who can work a computer. What a magnificent, momentous dream! And now it is coming true as more and more courses are made available on the Biblical Training website. May God prosper Biblical Training mightily! I cannot commend the venture too highly.” ~ J.I. Packer
