He was a convincing witness by the way he spoke. Words are vitally important. Words can excite or depress us. Words can encourage or discourage us. Words can make us glad, sad, or mad.
Words can inspire and lift our spirits, or defeat and deflate our souls.
Words can motivate and encourage, or they can crush and destroy. Words can convince us to stand tall for what is right, or they can dash hope and tarnish reputations. Words can offer a beautiful prayer and preach a powerful sermon, or they can incite a riot or defame the character of an innocent person. Profane words, bigoted words, cruel words do not promote the cause of Christ. They never have and they never will.
