20 So many and diverse, yea and more than these, are His witnesses: is then the Christ thus witnessed any longer disbelieved? Nay rather if there is any one who formerly believed not, let him now believe: and if any was before a believer, let him receive a greater increase of faith, by believing in our Lord Jesus Christ, and let him understand whose name he bears. You are called a Christian: be tender of the name; let not our Lord Jesus Christ, the Son of God, be blasphemed through you: but rather let your good works shine before men that they who see them may in Christ Jesus our Lord glorify the Father which is in heaven: To whom be the glory, both now and for ever and ever. Amen.
