Ignorance of the Bible is ignorance of Christ. You must bear witness as well.
Witnesses provide the information through which critical decisions are made.
The most important decision a human being can make is to decide for or against Christ. Thousands of people look at the witness of our lives to see whether they should decide for or against Christ. Many people have decided against accepting the radical demands of Jesus. This is their decision, but it may also indicate that Jesus' witnesses are too lukewarm, cowardly, or worldly to draw unbelievers to Jesus. Because witnessing is such a critical element in God's plan, Satan makes witnessing as difficult as possible.
