Rev. J.A Adewumi own Christian life developed because he took the Bible so seriously, and

 so the Life Reformer Bible Ministry has developed in the same way. His sermons were captivating,

“I would classify him as one of the greatest living preachers, giving a straightforward

Bible-based message, his sermons thorough, and always personally challenging. He always gave a wide

range of cross-references which were read in their context, supporting, clarifying and expanding his main points. He spoke clearly and authoritatively to the Nigerian situation. He dealt sensitively with African culture, but also made a firm stand in highlighting the points where local culture was incompatible with the will of God. While stressing the high moral tone which is one of the virtues of most African cultures at their best, he was at pains to specify those aspects of local culture which were unchristian and even evil. In this way he was not only concerned with some kind of personal holiness, but also genuinely seeking the wholeness and harmony of the community at large, where truth, honesty, and justice should be the predominant characteristics.
