You would be very hard-pressed to find a respectable historian who believes that Jesus did not exist. There is arguably more good evidence that Jesus existed than did Alexander the Great. Whether or not he did all the things he is reported to have done is perhaps another matter. The issue of Jesus’ existence, however, is so well established historically, that it is almost never seriously disputed.
...Jesus opens his arms to his needy children and says, "Come to Me, all who are weary and heavy-laden, and I will give you rest"(Matthew 11:28, NASB). The criteria for coming to Jesus is weariness. Come overwhelmed with life. Come with you wandering mind. Come messy.
