The most consistent presuppositional approach is to answer every objection with Scripture; Sye admits he gets too bogged down in philosophy and wants to recover a more Scripture-centered approach

Sye says the best street evangelist he ever heard was a heretic — but effective because he answered everything with Scripture. The presup method done faithfully is: start with God's Word, answer every objection with Scripture, don't get bogged down in epistemological philosophy. He admits his own method has sometimes lost that simplicity. He cites the Reformed emphasis on preaching as the instrument of salvation (sheep hear his voice).
