It becomes, then, the duty of those who know about the realities of the spirit to reveal these things to those who discern only the manifestations of the material world. But will you believe us if we tell you of the heavenly truths?

When you look upon me, you see not only the Son of Man but also Him who sent me. I am the light of the world, and whosoever will believe my teaching shall no longer abide in darkness. If you gentiles will hear me, you shall receive the words of life and shall enter forthwith into the joyous liberty of the truth of sonship with God. If my fellow countrymen, the Jews, choose to reject me and to refuse my teachings, I will not sit in judgment on them, for I came not to judge the world but to offer it salvation. Nevertheless, they who reject me and refuse to receive my teaching shall be brought to judgment in due season by my Father and those whom he has appointed to sit in judgment on such as reject the gift of mercy and the truths of salvation. Remember, all of you, that I speak not of myself, but that I have faithfully declared to you that which the Father commanded I should reveal to the children of men. And these words which the Father directed me to speak to the world are words of divine truth, everlasting mercy, and eternal life. similarity: 0.689726 rank: 2 headers: X-RateLimit-Limit: $ref: '#/components/headers/X-RateLimit-Limit' X-RateLimit-Remaining: $ref: '#/components/headers/X-RateLimit-Remaining' X-RateLimit-Reset: $ref: '#/components/headers/X-RateLimit-Reset' '400': description: Invalid request content: application/problem+json: schema: $ref: '#/components/schemas/ProblemDetails' headers: X-RateLimit-Limit: $ref: '#/components/headers/X-RateLimit-Limit' X-RateLimit-Remaining: $ref: '#/components/headers/X-RateLimit-Remaining' X-RateLimit-Reset: $ref: '#/components/headers/X-RateLimit-Reset' '404': description: Work or reference not found content: application/problem+json: schema: $ref: '#/components/schemas/ProblemDetails' headers: X-RateLimit-Limit: $ref: '#/components/headers/X-RateLimit-Limit' X-RateLimit-Remaining: $ref: '#/components/headers/X-RateLimit-Remaining' X-RateLimit-Reset: $ref: '#/components/headers/X-RateLimit-Reset' '429': description: Too many requests content: application/problem+json: schema: $ref: '#/components/schemas/ProblemDetails' headers: X-RateLimit-Limit: $ref: '#/components/headers/X-RateLimit-Limit' X-RateLimit-Remaining: $ref: '#/components/headers/X-RateLimit-Remaining' X-RateLimit-Reset: $ref: '#/components/headers/X-RateLimit-Reset' '500': description: Internal server error content: application/problem+json: schema: $ref: '#/components/schemas/ProblemDetails' headers: X-RateLimit-Limit: $ref: '#/components/headers/X-RateLimit-Limit' X-RateLimit-Remaining: $ref: '#/components/headers/X-RateLimit-Remaining' X-RateLimit-Reset: $ref: '#/components/headers/X-RateLimit-Reset' components: headers: X-RateLimit-Limit: description: The number of requests allowed in the current window. schema: type: integer example: 200 X-RateLimit-Remaining: description: The number of requests left in the current window. schema: type: integer example: 199 X-RateLimit-Reset: description: The time the window resets, in Unix seconds. schema: type: integer example: 1791152213 schemas: ProblemDetails: type: object description: An RFC 9457 problem details object.
