One simple fact: The central theme of Jesus' public preaching was not a new religion brand — it was the Kingdom of God. Across the Synoptic Gospels, that phrase (or Matthew's "Kingdom of Heaven") sits at the heart of his message from the start of his ministry.
"The time has come," he said. "The kingdom of God has come near. Repent and believe the good news!"
— Jesus, Mark 1:15 (NIV)
Historical backdrop
Jesus did not invent the language of God's kingdom. First-century Jews already prayed for God's reign to break in — for example in the ancient synagogue Kaddish: "May He let His Kingdom rule… speedily and soon." Scholarship on the Synoptics places Jesus' preaching inside that Jewish hope: God's rule drawing near, calling for repentance and trust. See the overview in this study of "Kingdom of God" in the Synoptic Gospels.
The Dead Sea Scrolls do not mention Jesus, but they do light up the Jewish world he lived in. One scroll, the Messianic Apocalypse (4Q521), lists miracles in an order close to Luke 7:21–22 — written about 150 years before Luke — showing shared Second Temple expectations about what God's saving reign would look like.
First-person: a near-death encounter with Jesus
Keith R. recounts flatlining in ICU as a child, rising above his body, traveling a tunnel, and meeting Jesus, who told him, "It's not your time." He published the account with the Near Death Experience Research Foundation:
Another documented testimony: Randy Kay describes dying from septic shock, calling on Jesus' name, and being embraced by Christ before being sent back. Reported by CBN News.
First-person: visitation of Jesus and the Holy Spirit
Sister Prema Pelletier records a childhood dream-visitation in which Jesus knelt beside her, wiped her tears, and spoke John 16:23 over her — and later a powerful Holy Spirit presence that left her "marveling at the goodness of our great God." Her firsthand write-up:

Why this matters
Jesus announced a Kingdom that was near — not merely a far-off afterlife, and not merely inner sentiment. History shows that hope was already alive in Jewish prayer and apocalyptic expectation. Modern first-person accounts keep pointing back to the same Person at the center of that Kingdom: Jesus himself.
